Overview
The Polyamp PM150C24 is a robust industrial DC/DC converter engineered for reliable power conversion in harsh environments. This switching-mode converter accepts a wide input voltage range (50–150V DC) and outputs a stable 24V DC at up to 6.25A, delivering 150W of power. The PM150C24 is designed for mounting in standard 19″ racks and is ideal for telecom, industrial automation, switchgear, and control system applications.
Key Features
- Wide Input Voltage Range: Accepts 50–150V DC input, tolerating voltage fluctuations from diverse power sources
- Stable 24V DC Output: Delivers up to 6.25A (150W) with excellent line and load regulation
- Overvoltage Protection (OVP): Limits output voltage to 15% above nominal, protecting downstream equipment
- Redundant Power Configuration: Series diode output allows multiple units to operate in parallel for N+1 redundancy
- Over/Under Voltage Alarm: User-configurable relay output (30V, 0.5A rated) for NO/NC alarm signaling
- 19″ Rack Mount: DIN-rail or chassis mounting compatible; convection-cooled design
