PULS CD5.242 DIN-Rail DC/DC Converter, 48V to 24V, 5A, 120W, Isolated
PULSThe PULS CD5.242 is a DIN-rail mounted DC/DC converter that steps a 48 V DC input down to an isolated, regulated 24 V DC output rated at 5 A / 120 W. Part of the PULS DIMENSION C-series, it fits in a compact 32 mm-wide housing and combines galvanic input-to-output isolation, reverse-polarity protection, and an integrated soft-start with a broad slate of global agency approvals. The CD5.242 is built for 48 V battery and DC distribution systems, machine building, material handling, and process environments where a clean, protected 24 V control voltage is required.
Key Features
- 48 V DC input with a wide 36 - 60 V DC range (48 V ±25%)
- Isolated, regulated 24 V DC output, adjustable from 24 - 28 V
- 5 A at 24 V / 4.3 A at 28 V, 120 W rated output power
- Up to 90.3% typical efficiency keeps heat dissipation low (12.9 W typical losses)
- 20% PULS Power Boost reserve, usable continuously up to +45°C ambient
- Full 120 W rated output from -25°C to +60°C
- Compact 32 mm width conserves DIN-rail and control-panel space
- Integrated soft-start function and minimal input inrush current surge
- Reverse input polarity protection
- Screw-terminal connections for fast, secure field wiring
