Features:
- Redundant and N+1 configurations,Hot replaceable Power Packs
- Current sharing,Current limiting,Power factor correction
- Diagnostic contacts,Configurable output voltage,Input/output fail diagnostics per power pack
The Power Pack is specifically designed to operate as an integral part of a complete distributed Power System. A full complement of protection, alarm and control features has been incorporated into the Power Pack to provide versatility for use in many applications. Power Packs can be inserted and removed when live, allowing ‘hot-swap’ of Power Packs. They are secured using a physical latch on the front of the Power Pack which is pushed up to release or connect the Power Pack into the Power Shelf.
The Trusted® Power System is a high density flexible power supply designed to convert main line voltages of either 110 Vac or 240 Vac. Outputs are either 24 Vdc for Trusted product or 28 Vdc adjustable field power.
The T8231C ICS Triplex Trusted Power Pack may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Active Load Balancing: Built-in active current balancing circuitry. When connected in parallel in a power supply rack, multiple units can evenly distribute the system load, keeping load imbalance within ±5%.
Millisecond-Level Fault Takeover: If a single module fails, the parallel online modules will dynamically take over the entire system load within milliseconds, ensuring zero downtime.
Hot-Swap Slots: Supports online hot-swapping via SmartSlot connection, allowing for physical replacement without interrupting operation or disconnecting field circuit power.
Overcurrent Voltage Derating: If peak load demand is too high, the device will safely reduce the voltage to 18.75V (current limited to 40A) instead of tripping completely, thus keeping the system modules barely online.
The T8231C power module is primarily based on a high-frequency switching power supply (SMPS) inverter topology and hardware current sharing technology. When a 110V or 240V AC power supply is input, its internal rectification, filtering, and power factor correction (PFC) circuitry first converts it to high-voltage DC, which is then modulated into high-frequency pulses by high-frequency switching elements (approximately 30 kHz).
These high-frequency pulses are then stepped down by a high-frequency transformer and electrically isolated, finally converted to a low-voltage, high-purity 24V DC output by a synchronous rectification and filtering circuit.
When multiple modules are connected in parallel, the analog control loop within each T8231C dynamically monitors its own output current and compares it in real-time with the current of other modules via a current sharing bus on the rack backplane. This allows for fine-tuning of its PWM duty cycle, ensuring highly accurate and balanced load distribution among the modules.
