Technical Specifications

Input voltage: AC 208–240V, 50/60Hz (single phase)

Output voltage / current:

+5V DC / 3A (control logic)

±15V DC / 1.5A (op-amp / signal)

+24V DC / 2A (relay / excitation)

Efficiency: ≥85% (full load)

Operating temperature: 0–50°C; Storage: -20–70°C

Dimensions (width × height × depth): approximately 45×220×180mm

Weight: approximately 2.1kg

Installation: Special slot on the left side of the PMI rack, fixed on the front panel

Insulation withstand voltage: Input - Output 2kV AC/1min

Interface and communication configuration

Front panel:

P1: AC input (L/N/Ground)

P2: DC output terminal block (+5V, ±15V, +24V, common ground)

LED: Green "PWR OK" (normal always on, fault off / flashing)

Back panel: No communication, only gold fingers for auxiliary fixation and grounding

Communication: No independent communication port, status read by the system control card Core function

Multi-channel Isolated Power Supply: Converts single-phase AC to multiple isolated DC, meeting different requirements for control, signals, and excitation.

Overvoltage / Overcurrent / Short-circuit Protection: Output short-circuit self-limiting current, overvoltage clamping, overheating shutdown, protecting the downstream boards.

Surge Suppression: Built-in lightning protection / surge absorption on the input side, resisting grid fluctuations.

Power Supply Redundancy Compatibility: Supports dual-module parallel operation (requires the same version), automatic fault switching.

Low Ripple Output: High-frequency switching design, ripple < 50mV, ensuring control accuracy. Applicable scenarios

Industrial direct current drive: Large power DC motors are used to drive equipment such as rolling mills, paper machines, extruders, cranes, conveyors, etc.

PMI system original equipment / replacement: Compatible with all PMI racks (such as the 57C series), directly replacing 0-60007-1.

Maintenance for outdated production lines: Replacement of spare parts for out-of-service equipment to avoid entire line renovation and reduce costs.

User and maintenance instructions Installation

Only for the left slot of the PMI rack, perform power-off installation, tighten the panel screws; do not perform hot swapping.

Input: Connect the power line with a 5A fuse, ensure reliable grounding.

Connections

AC input: L/N/ Ground, wire diameter ≥ 1.5mm², keep away from power lines.

DC output: Connect according to the markings, avoid short circuits of positive and negative poles; single-ended grounding for the shielded wire.

Daily maintenance

Power off and blow dust every 3-6 months, check if the terminals are loose or burned.

Observe the "PWR OK" light: always on indicates normal; flashing indicates overload / overheating; off indicates input power failure / module damage.

Troubleshooting

No output: Check AC input, fuse, connection terminals; no light → module damage.

Unstable output: Check input voltage fluctuations, load short circuits, blocked cooling airways.
