 Uses and Key Features OF Edwards signal PS10-4B power supply card

The Edwards PS10-4B Power Supply Card is a high-performance power supply module specifically designed for Edwards EST3X fire alarm control systems. It plays a critical role in ensuring reliable operation by supplying regulated 24VDC power to the control panel, rail chassis modules, notification appliance circuits (NACs), and other ancillary devices. In addition to providing stable power, the PS10-4B continuously supervises the power system, helping maintain compliance with fire safety standards and ensuring uninterrupted operation during emergency situations. The module supports both AC mains input and rechargeable backup batteries, allowing the fire alarm system to continue operating during power failures. It is engineered for commercial, industrial, institutional, and large-scale building applications where dependable fire protection is essential.

The PS10-4B features universal AC input ranging from 94 to 264 VAC (50/60 Hz), making it suitable for installations in different regions without additional voltage conversion. It delivers regulated 24VDC output with a maximum supply rating of 10A (UL) for powering notification appliances, auxiliary equipment, and other connected devices. The card includes four supervised notification appliance/auxiliary power circuits that can be configured for various system requirements. It also supports battery charging for standby batteries up to 35Ah, ensuring backup power is always available when utility power is interrupted.

One of the major advantages of the Edwards PS10-4B is its built-in supervisory capabilities.
