This document describes the characteristics of the 46 Unit Type Power Supply DSR30 model, including UL CSA certification, nominal output voltage, maximum output current, maximum output power, input voltage range, output voltage range, line regulation, load regulation, cooling method, operating ambient temperature, withstand voltage, and vibration.
The DSR series from Lambda provides compact, single‑output DC power supplies covering output powers of 30 W, 50 W and up to 180 W. Models support various input voltages (24 V or 48 V DC, and 110 V DC versions) and deliver adjustable output voltages from 5 V to 48 V (or 2 V to 48 V for the 110 V input line).\n\nKey specifications include tight line and load regulation, operation from –20 °C to +71 °C, and robust protection functions such as over‑voltage, over‑current, thermal and low‑input safeguards. The units feature convection cooling, optional forced‑air cooling, and a five‑year warranty. Mounting diagrams and recommended noise‑filter accessories are provided for easy installation.
| Input voltage range (24 V version) | DC 18 V ~ 32 V |
|---|---|
| Input voltage range (48 V version) | DC 32 V ~ 63 V |
| Output voltage range (24 V/48 V models) | 5 V ~ 48 V |
| Line regulation | 0.4 % |
| Load regulation | 0.8 % |
| Operating temperature range | -20 °C ~ +71 °C |
| Withstand voltage (standard models) | 1.5 kVAC input‑output |
| Vibration resistance | Maximum 5 G |
All DSR models come with a five‑year warranty.
The units provide over‑voltage, over‑current, thermal, low‑input protection, power‑failure detection and remote on/off control.
The devices operate from –20 °C up to +71 °C.
The 24 V version accepts 18‑32 V DC, the 48 V version accepts 32‑63 V DC, and a 110 V DC version is also available.
