The Basler Electric 9310200100 is a compact, regulated DC power supply module designed to provide stable power to protective relays, logic controllers, and auxiliary equipment in substations and industrial facilities. It converts an AC input (typically 120 or 240 VAC) into a clean DC output, ensuring reliable operation of sensitive electronic devices under varying load conditions. The module is ideal for panel mounting and offers high efficiency and low ripple.
Input voltage: 100‑240 VAC, 50/60 Hz (or 110‑350 VDC optional). Output voltage: 24 VDC nominal, adjustable ±10%. Output current: up to 3 A (72 W) or higher depending on variant. Regulation: ±1% for load and line variations. Ripple and noise:<50 mv="" peak.="" efficiency:="">85% at full load. A green LED indicates output presence.
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.
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.
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.
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.
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.
The Basler Electric 9310200100 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.
