PLCs, Power Supplies & Others

This power supply unit converts AC mains voltage into stable DC power for industrial control systems. It delivers consistent output to PLCs, drives, and instrumentation panels. The device features built-in overload protection for safe and durable operation.

Technical Specifications

Mechanical Construction and Mounting

This power supply features a rugged metal housing that shields internal components from physical damage. Its compact 60 mm wide design saves valuable panel space. The unit weighs 0.70 kilograms and offers both DIN-rail and panel-mount options. All terminal covers provide finger-safe protection against accidental contact.

Input Power and Conversion Efficiency

The device accepts a universal AC input range from 100 to 240 volts. It automatically adjusts to line frequencies between 47 and 63 hertz. The efficiency reaches 87 percent at nominal full-load conditions. This performance reduces energy waste and lowers cabinet cooling demands.

Output Characteristics and Regulation

This power supply delivers a stable 24 V DC output with a precision of ±2 percent. It provides a continuous output current of 6.5 amperes for moderate loads. The maximum output power reaches 156 watts under nominal conditions. The output ripple remains below 60 mV peak-to-peak for clean power delivery.

Protection Mechanisms and System Safety

The unit integrates comprehensive protective circuits for reliable operation. Overcurrent protection limits the output during short-circuit events. Overvoltage clamping prevents damage to downstream sensitive electronics. An overtemperature shutdown turns off the module if internal temperatures become excessive.

Energy Storage and Ride-through Capability

Built-in electrolytic capacitors store sufficient energy for a 15-millisecond hold-up time. This reserve allows the module to bridge momentary power interruptions. The hold-up feature prevents controller resets during grid fluctuations. This capability maintains process continuity in unstable supply conditions.

Thermal Management and Cooling Design

The fanless design relies on natural convection for heat dissipation. This passive cooling approach eliminates mechanical wear and noise. The housing includes ventilation slots for optimal airflow. The unit operates reliably across temperatures from -10°C to +60°C.

Operational Indicators and User Interface

One front-panel LED provides clear visual status indication. The green LED illuminates when the output voltage is present and stable. The unit also includes a potentiometer for fine output voltage adjustment. This trimmer allows users to compensate for voltage drops in long cables.

Application Versatility

This power supply serves a wide range of industrial automation equipment. It works effectively in control cabinets, machine tools, and conveyor systems. The device also supports building management and HVAC control applications. Its robust construction ensures dependable performance in demanding factory environments.
