Product Details

VT25-373-99/X9 Product Description

The Kongsberg VT25-373-99/X9 is a precision-engineered power supply module designed for energy-critical industrial automation environments. Built within Kongsberg's proven VT25 Series platform, this module delivers stable, regulated DC power to control systems where energy efficiency, load reliability, and thermal management are non-negotiable. Whether deployed in offshore automation cabinets, maritime control systems, or onshore smart factory infrastructure, the VT25-373-99/X9 serves as the backbone of a power-aware automation strategy — reducing unnecessary energy draw, minimising heat generation, and sustaining consistent production line throughput.

In modern industrial facilities, unregulated or inefficient power distribution is one of the leading contributors to elevated energy costs and unplanned downtime. The VT25-373-99/X9 addresses this directly by providing clean, conditioned power output that protects downstream components from voltage fluctuations, inrush current spikes, and harmonic distortion — all of which degrade both equipment lifespan and energy efficiency. Its compact form factor and DIN-rail-compatible design allow seamless integration into existing control panel architectures without requiring significant re-engineering of the power distribution layout.

The VT25-373-99/X9 is engineered to operate as a central power node within a broader energy-aware control architecture. In a typical smart factory deployment, this module supplies conditioned power to a Kongsberg VT25 PLC CPU module, ensuring that the controller maintains stable clock cycles and deterministic scan times even under variable load conditions. Alongside the CPU, the module feeds power to VT25 digital I/O expansion modules, which handle real-time field signal acquisition from proximity sensors, limit switches, and process feedback devices — all of which are critical for accurate energy state monitoring.

When integrated with a Kongsberg VT25 analogue input module, the power supply enables precise current and voltage measurement from field instruments, supporting real-time load profiling across the production line. This data feeds directly into the SCADA supervisory layer, where energy consumption trends are visualised, logged, and used to trigger demand-response actions — such as shedding non-critical loads during peak tariff windows or ramping down auxiliary drives during scheduled idle periods.

On the drive side, the VT25-373-99/X9 supports the control power requirements of variable frequency drive (VFD) control boards and servo drive auxiliary circuits, ensuring that motor speed regulation and torque control remain stable regardless of mains voltage fluctuations. This is particularly important in applications where AC induction motors or permanent magnet servo motors are operating under variable load profiles — conditions where unstable control power can cause erratic drive behaviour, increased motor heating, and elevated energy consumption.

The module also interfaces cleanly with Kongsberg VT25 communication gateway modules supporting protocols such as PROFIBUS DP and PROFINET IO, enabling the power supply status and load metrics to be reported upstream to the plant-level energy management system (EMS). When paired with a power monitoring module on the same backplane, operators gain granular visibility into per-module power consumption — a prerequisite for ISO 50001 energy management compliance and continuous improvement programmes.

For HMI-driven energy dashboards, the VT25-373-99/X9's operational status can be surfaced on a Kongsberg operator panel or third-party HMI terminal, giving line operators immediate visibility into power supply health, output voltage stability, and any fault conditions — without requiring access to the engineering workstation.

In high-throughput manufacturing environments, power supply instability is a silent productivity killer. Voltage sags, ripple noise, and inadequate current headroom cause intermittent faults in PLCs, I/O modules, and communication interfaces — faults that are difficult to diagnose and often misattributed to software or network issues. The Kongsberg VT25-373-99/X9 eliminates this class of problem by providing a clean, stable power foundation that the entire control system can rely on.

From an energy optimisation perspective, the module's efficient power conversion topology minimises the gap between input power drawn from the mains and useful output power delivered to the control system. This directly reduces the facility's base electrical load — a meaningful contribution in large installations with dozens of control panels operating continuously across three-shift production schedules.

Thermal management is equally important. Inefficient power supplies generate excess heat that must be removed by panel cooling systems — fans, heat exchangers, or air conditioning units — all of which consume additional energy. The VT25-373-99/X9's low heat dissipation profile reduces the cooling burden on the enclosure, extending the service life of adjacent components and reducing the total energy footprint of the control panel.

For predictive maintenance programmes, the stable output characteristics of the VT25-373-99/X9 provide a reliable baseline against which anomalies can be detected. A gradual increase in output ripple or a drift in regulated voltage — when monitored via the SCADA system — can indicate capacitor ageing or thermal stress before a failure occurs, allowing maintenance teams to schedule replacement during planned downtime rather than responding to an unplanned outage. This approach directly improves Overall Equipment Effectiveness (OEE) and reduces the energy waste associated with emergency restart procedures and production catch-up cycles.

All units are supplied from verified in-stock inventory, pre-tested under load conditions, and dispatched with full documentation. The 12-Month Warranty covers manufacturing defects and functional failures from the date of shipment, providing procurement teams with the confidence to standardise on the VT25-373-99/X9 across multiple production lines and facility locations.

Q1: What energy efficiency benefits does the VT25-373-99/X9 deliver in a production line context? The VT25-373-99/X9 reduces idle-state power draw by providing precisely regulated output with minimal conversion losses. By stabilising the power supply to PLC CPUs, I/O modules, and communication gateways, it eliminates the micro-interruptions and voltage fluctuations that force control systems into fault-recovery cycles — each of which consumes additional energy and disrupts production throughput. The result is a more consistent line cycle time and a measurable reduction in control-system-related energy waste.

Q2: Is the VT25-373-99/X9 compatible with third-party PLCs, SCADA systems, and VFD control circuits? The module is natively designed for the Kongsberg VT25 platform but its regulated DC output is compatible with a wide range of industrial control equipment operating within the same voltage class. It can supply auxiliary power to VFD control boards, servo drive logic circuits, and communication modules from other manufacturers, provided the voltage and current specifications are matched. For SCADA integration, power supply status can be monitored via the VT25 communication gateway using standard industrial protocols.

Q3: Can the VT25-373-99/X9 replace an existing power supply module in a legacy Kongsberg system? Yes. The VT25-373-99/X9 is a direct replacement candidate for compatible VT25 Series power supply positions. Before installation, verify the output voltage rating, current capacity, and backplane connector pinout against the existing module specification. All replacement units supplied by NANKMOS are pre-tested under load conditions and include a 12-Month Warranty from the date of shipment, making them a reliable choice for both planned upgrades and emergency replacements.

Q4: What is the testing and dispatch process, and what does the 12-Month Warranty cover? Every VT25-373-99/X9 unit undergoes a full functional and load test prior to dispatch. This includes output voltage verification, ripple measurement, and thermal stability assessment under rated load conditions. Units are dispatched from in-stock inventory, typically within 1–3 business days of order confirmation. The 12-Month Warranty covers manufacturing defects and functional failures under normal operating conditions from the date of shipment. Warranty claims are handled directly through NANKMOS with priority support for production-critical applications.
