Information About 2-PPS/6A
The 2-PPS/6A is part of the Edwards PPS Series of primary power supplies, built to provide 24 VDC nominal output for system modules and notification appliance circuits (NACs). It includes integral battery charging capabilities up to 24 Ah and safeguards against total battery discharge during alarms. Designed for installation in fire alarm systems, the unit uses MOV and common mode choke protection against AC transient spikes. This model operates at 120 VAC input and offers dependable Class B circuit support with a compact design for control panel integration.
Key Features:
- Switch-Mode Design: Efficiently converts input power to stable 24 VDC output.
- Output Capacity: Provides up to 6.4 A of current for system modules and devices.
- Battery Charging: Supports battery charging up to 24 Ah capacity.
- Dual NAC Outputs: Includes two supervised 24 VDC outputs for notification appliances.
- Ground Fault Testing: Continuously monitors AC line and system grounding.
- Automatic Backup Transfer: Ensures seamless switchover to battery during AC failure.
- AC Protection: MOVs and common mode choke filter protect against voltage transients.
- Compact Integration: Mounts easily in control panels with straightforward wiring.
- Environmental Tolerance: Operates in 32°F to 120°F (0°C to 49°C) and up to 93% humidity.
- UL Application: Suitable for powering Edwards fire alarm systems and NAC circuits.
The 2-PPS/6A delivers the reliability and performance required for powering Edwards fire alarm systems.
