Read MoreThe Polyamp PC2000 Series DC/DC Converter is a high-performance power solution designed for demanding industrial, railway, and telecommunications applications. Delivering up to 2000W of power, it ensures reliable and efficient operation in challenging environments.
Key features include a wide input voltage range (20–300 V DC) and single output options from 24V to 53.3V DC, with a high efficiency exceeding 89%. The PC2000 Series is equipped with advanced functionalities such as current sharing for parallel operation, external output voltage sensing for precise regulation, and inrush current limiting for enhanced protection. Additional safety features include reverse input voltage protection, overvoltage protection (OVP), and an alarm relay for over/undervoltage conditions.
The PC2000 Series supports both convection cooling (up to 1000W) and fan cooling (up to 2000W), with an operating temperature range of -25°C to +55°C (expandable to +70°C with derating). Its flexible design accommodates wall mounting, DIN rail installation, and 19” rack configurations, ensuring seamless integration into a variety of systems.
The Polyamp PC2000 Series is the ideal choice for efficient, scalable, and robust power conversion.

| FEATURES | |
|---|---|
| Current sharing | Current sharing is used to balance the load between up to 10 units working in parallel |
| External output voltage sense | External sense is used when the voltage regulation at the load is critical. The sense can compensate voltage drops up to 5% of nominal voltage |
| Alarm circuit | The alarm relay swtches to "Alarm" state if the output is not within -10% to +15% of nominal output voltage, or the converter is overheated |
| Over voltage protection OVP | A second regulation circuit takes over in case the main regulation fails. The output voltage is limited to approximately +15% over nominal output voltage |
| Inhibit input Power down | The converter will shutdown if the inhibit input is short circuit by a relay or electrical switch. The current through the short-circuit is 20mA |
| OPTIONAL FEATURES | |
|---|---|
| Conformal Coating | For environment with high non-condensing humidity max 98% RH |
| Series diode on output | Specify series diode output when the output is connected in parallel with other power supply to achieve redundancy. The output is derated 10% on 24V and 5% on 48V |
