GLP Switching Power Supply DL2-100-48-U | 100.8W 48V DIN Rail Industrial PSU

The GLP DL2-100-48-U stands apart from typical DIN rail power supplies by combining a wide 85–264 VAC input range with a robust 100.8 W output in a compact, convection-cooled housing. It is built for industrial control panels, building automation, and machinery where stable 48 VDC power is non-negotiable. Unlike basic models, this unit offers adjustable output voltage up to 55 VDC, full protection against overload, overvoltage, short circuit, and overtemperature, plus 3000 VAC input-output isolation for extra safety.

Highlights

• Output: 48 VDC, 2.1 A, 100.8 W continuous power
• Universal input: 85–264 VAC or 120–370 VDC
• High efficiency >88% and low ripple & noise <150 mVp-p
• Adjustable output voltage from 48 to 55 VDC via front-panel potentiometer
• DIN rail mounting on TS-35/7.5 or TS-35/15 rails
• Free air convection cooling – no fan, no maintenance
• Full protection: overload, overvoltage, short circuit, overtemperature
• Wide operating temperature range: -20°C to +70°C
• MTBF >300,000 hours for long service life
• CE and RoHS certified

In daily use

Installation is quick thanks to the snap-on DIN rail clip. The slim profile saves space in crowded enclosures, while the rugged metal housing withstands industrial environments. The output voltage can be fine-tuned to compensate for voltage drops in long cable runs, making it ideal for powering sensors, relays, PLCs, and other 48 VDC equipment. The wide temperature tolerance ensures reliable operation even in poorly ventilated cabinets or harsh conditions.
