The HITACHI PS6524 is a high-performance switching power supply designed to deliver stable 24 VDC power for industrial automation systems. With an output capacity of 2.5 A, it is capable of powering a wide range of loads including PLCs, sensors, small actuators, and indicator lights. The unit accepts a universal AC input (100–240 VAC) and features a compact, slim profile that mounts directly on standard DIN rails, saving valuable panel space. Its robust construction and comprehensive protection features ensure long-term reliability in demanding environments.
Universal AC Input: 100–240 VAC (50/60 Hz) with active power factor correction (PFC) to minimize harmonic distortion.
Stable 24 VDC Output: 24 VDC ±1% regulation at 2.5 A continuous (3.5 A peak for 5 seconds).
High Efficiency: Up to 88% efficiency reduces heat generation and energy costs.
Comprehensive Protections: Overload (110–150%), short-circuit (auto-recovery), overvoltage (30–36 VDC shutdown), and overtemperature protection.
LED Status Indicator: Green LED for output OK, red for overload or fault.
DC OK Relay Contact: Form C relay (1A/30VDC) for remote monitoring of output status.
Compact DIN Rail Mount: Width only 45 mm, ideal for space-constrained cabinets.
Input Voltage: 100–240 VAC (50/60 Hz), 140–340 VDC
Output Voltage: 24 VDC ±1%
Output Current: 2.5 A continuous, 3.5 A peak (5 s)
Ripple & Noise: ≤ 50 mV p-p (20 MHz bandwidth)
Efficiency: ≥ 88% at 230 VAC full load
Hold-up Time: ≥ 20 ms at 115 VAC
Protection: Overcurrent, short-circuit, overvoltage, overtemperature
Operating Temperature: -10°C to +60°C (derating above 50°C)
Dimensions (W×H×D): 45×90×100 mm
Certifications: CE, UL 508, cUL, RoHS

The PS6524 is commonly used in industrial control panels to power PLC racks, distributed I/O, field sensors (proximity, pressure), and small DC motors. It is also ideal for powering HMIs, communication converters, and alarm systems. The DC OK relay can be wired to a PLC input to trigger an alarm if the power supply fails, enhancing system uptime.
The power supply snaps onto standard 35 mm DIN rails (TS35) and requires no tools for installation. Input and output terminals are clearly marked and accept up to 2.5 mm² wires. The unit can be mounted in any orientation, but proper ventilation should be maintained. Multiple PS6524 units can be paralleled for redundancy (with external diodes) or connected in series for higher voltages (up to 48 V).
Designed to meet industrial standards, the PS6524 is tested for immunity to electrical fast transients, surges, and electrostatic discharge (IEC 61000-4). It operates reliably in ambient temperatures up to 60°C (with derating) and is protected against short-term condensation. The unit is RoHS compliant and carries CE and UL marks for worldwide use.
With its compact size, high efficiency, and robust protection, the HITACHI PS6524 switching power supply is an excellent choice for ensuring reliable power distribution in any industrial automation project.
