Basler Electric 36T865-2 BE03752001 Power Supply

The Basler Electric 36T865‑2 (BE03752001) is a compact, high‑efficiency power supply intended for powering protective relays, control logic, and auxiliary devices in electrical substations and industrial control panels. It converts standard AC mains into a stable DC output with excellent regulation and low electrical noise. Its small footprint and simple installation make it ideal for retrofitting or new panel designs.

Electrical Characteristics

Input: 120 or 240 VAC (selectable), 50/60 Hz. Output: 24 VDC nominal, adjustable over a range of ±10%. Output current capacity is typically 1‑3 A depending on version, with overload and short‑circuit protection. The unit features less than 1% output voltage variation over full load and line changes. Ripple is below 30 mV RMS to ensure interference‑free operation of sensitive electronics.

Mechanical and Environmental

The power supply is housed in a durable steel casing with a powder‑coated finish, suitable for panel mounting via keyhole slots or DIN rail (with optional adapter). Operating temperature range is –25°C to +65°C, with natural convection cooling. The unit is sealed against dust and moisture to IP20 rating. Terminal blocks are clearly labelled for input, output, and grounding.

Protection and Safety

Built‑in protections include input over‑voltage protection (MOV), output over‑voltage clamping, current limiting, and thermal shutdown. The power supply automatically recovers after fault conditions. It meets UL 508, CSA C22.2, and EN 60950 safety standards, with reinforced insulation and low leakage current.

Applications

This power supply is used in protection relay panels, annunciator systems, RTU cabinets, and small PLC installations. It is also employed in telecommunication power systems and railway signaling. Its reliability is critical for continuous monitoring and control functions.

Installation and Operation

Mount the unit on a flat surface using the provided hardware. Connect the AC input wires to the L, N, and ground terminals; connect the DC output to the load with correct polarity. No user configuration is required. An LED indicator illuminates when the output is present. To test, measure the output voltage with a voltmeter.

Reliability and Service Life

Basler Electric designs this power supply for long life with high‑quality components and conservative derating. The unit is subjected to temperature cycling, vibration, and humidity testing. With proper installation, the expected service life exceeds 10 years under normal operating conditions.

Conclusion

The Basler Electric 36T865‑2 BE03752001 power supply is a dependable and economical choice for low‑power DC supply needs in control and protection systems. Its compact size, robust construction, and comprehensive protections ensure safe and uninterrupted operation.
