III. Main Functions

HPM/APM System Main Power Supply

Provides stable 25V DC for Honeywell TDC3000 / TPS / UCN control stations, driving controllers, I/O cards, communication cards, UCN network cards, etc.

Wide Voltage Adaptive

85–264VAC globally applicable, adaptable to grid fluctuations and unstable factory voltages.

Battery Backup and Charging Management

Connects to 48VDC battery pack for seamless switching, and includes a built-in charging circuit, automatically floating charging the battery.

AC Synchronous Signal Output

6VAC synchronous signal for system clock / timing synchronization, ensuring synchronous operation of control logic.

Parallel Redundancy, No Single Point Failure

Multiple power supplies can be directly paralleled, faults are automatically isolated, the system does not lose power, meeting high availability scenarios in petrochemical, power generation, nuclear power, etc.

Overvoltage / Overcurrent / Overheat Protection

Built-in complete protection circuit: output short circuit, overcurrent, overvoltage, overheat automatic shutdown / current limiting, protecting the load and the power supply itself. Annual: Load testing of output voltage, redundant switching test.

Common faults

Power indicator light not on: Input circuit breaker tripped, fuse blown, fan stuck.

Low output voltage: Overloaded load, environmental overheating causing voltage reduction, battery mode power supply.

Redundant switching failure: Parallel connection error, inconsistent power supply models, abnormal battery voltage.
