Basler Electric 9261500101 Power Supply Module

The Basler Electric 9261500101 (also referenced as 9 2615 00 101) is a robust DC power supply module designed to deliver clean, regulated power to protective relays, logic controllers, and auxiliary equipment in substations and industrial facilities. It converts an AC or DC input (depending on version) into a stable low‑voltage DC output, ensuring reliable operation of sensitive electronic devices under varying load conditions.

Electrical Specifications

Input voltage: 100‑240 VAC, 50/60 Hz (or 110‑350 VDC optional). Output voltage: 24 VDC nominal, adjustable ±10%. Output current: up to 5 A (120 W). Regulation: ±1% for load and line variations. Ripple and noise:<50 mv="" peak.="" efficiency:="">85% at full load. The module includes a green LED for output presence and a red LED for fault indication.

Protection Features

Built‑in protections include over‑voltage clamping, over‑current limiting, short‑circuit protection, and thermal shutdown. The unit automatically recovers from fault conditions once the overload is removed. Input is protected by a fuse and a surge suppressor. A dry‑contact alarm output is available to signal loss of output or internal fault.

Mechanical and Environmental

The module is housed in a rugged metal enclosure with screw‑type terminals for secure wiring. It is designed for DIN‑rail or panel mounting. Operating temperature range: –25°C to +65°C. Humidity: up to 95% non‑condensing. The unit is convection‑cooled, requiring no fan, which enhances reliability. It meets IP20 protection rating.

Applications

This power supply is ideal for powering Basler Electric BE1‑series relays, SR‑series voltage regulators, RTUs, PLCs, and communication devices. It is widely used in utility substations, industrial control rooms, and renewable energy facilities where a stable DC source is essential. It can also be used as a battery charger for small backup batteries.

Installation and Operation

Mount the module on a DIN rail or directly on a panel using the provided clips. Connect the AC/DC input leads to the designated terminals, observing correct polarity for DC input. Connect the output terminals to the load. The unit is ready to operate upon power‑up; no configuration is required. Output voltage can be trimmed using a potentiometer if adjustment is needed.

Reliability and Quality

Basler Electric manufactures this power supply under strict quality control, with each unit undergoing full load testing and dielectric strength verification. The use of high‑grade capacitors and transformers ensures long service life. The module complies with UL 508, CSA C22.2, and CE standards. Mean time between failures (MTBF) is rated at over 100,000 hours.

Conclusion

The Basler Electric 9261500101 power supply module is a dependable, efficient, and compact power source for critical control and protection systems. Its robust protection features and wide input range make it a versatile choice for a variety of industrial and utility applications.
