GWPS Series DC Power Supply Systems Panels

• The GoWatron GWPS-110V/220V-200Ah is an integrated station DC power supply system designed for substations, power plants, renewable energy facilities and industrial power distribution projects. Its typical rated DC voltage is 110 V DC or 220 V DC, with a 200 Ah battery bank.
• The system provides a stable and reliable DC supply for protection relays, bay control units, circuit-breaker trip and close circuits, signalling systems, communication equipment and emergency lighting.
• Under normal operating conditions, the high-frequency switch-mode charger modules supply the connected DC loads while charging the battery bank. If the AC auxiliary supply fails, the battery bank immediately supplies the essential DC loads, ensuring the uninterrupted operation of protection, control, signalling, communication and circuit-breaker operating circuits.
• The system provides intelligent monitoring, automatic battery charging, DC insulation monitoring, fault alarms and remote communication. In addition to 110 V DC and 220 V DC, GoWatron can provide systems rated at 24 V DC, 48 V DC and 125 V DC, as well as other customised voltage levels.
• The battery capacity, charger module ratings, outgoing feeder configuration, DC busbar arrangement and panel construction can all be customised to meet specific project requirements.

System Composition;
The GWPS-100AH DC Power Supply System/Panel is mainly composed of an AC distribution unit, charging rectifier modules, a silicon diode voltage-dropping chain, a DC feeder unit, a distribution monitoring unit, a master monitoring module, and an insulation monitoring unit.

Core Function;
This DC Power Supply System/Panel supplies stable operating power for circuit breaker closing/tripping operations of switching equipment in substations and power plants, as well as power for instruments, meters, and protection relays in secondary circuits.

Load Capacity;
A fully configured GWPS-100AH DC Power Supply System/Panel can typically power and support up to 15 high-voltage switchgear panels.

Models & Battery Configurations;
Two standard versions are available for the GWPS-100AH series: GWPS-DC110V/100AH and GWPS-DC220V/100AH.
