Information About 5120-9174
The 5120-9174 is a 165-watt regulated power supply from Simplex, built to support the 5110, 5120, and 5130 Building Communications Systems as well as 6333-9018 digital clocks. It features three Class 2 outputs rated at 24 VDC and 2 Amps each, all safeguarded by auto-resetting fuses for dependable overload protection. Its switching regulator maintains output voltage within ±2% under varying load and input conditions, ensuring precise performance. With protective measures against overvoltage and current overloads, this model is optimized for critical facility communication and timing equipment.
Key Features:
- Regulated Power Output: Provides 24 VDC at 6 Amps with ±2% voltage regulation.
- Multiple Outputs: Three independent Class 2 outputs rated at 2 Amps each.
- Overload Protection: Auto-resetting fuses safeguard outputs from excess current.
- Primary Fuse Protection: 3 Amp slo-blo fuse shields the AC input.
- Overvoltage Limiting: Automatically restricts output to ~28 VDC in case of failure.
- Parallel Connection Capability: Outputs may be paralleled to increase available current.
- System Compatibility: Designed for Simplex digital clocks and building communication systems.
The 5120-9174 delivers the reliability and precision required for stable power distribution in communication and timing applications.
