Applications
- Stabilized DC power supply: Provides controlled, isolated 24 V DC power from a 3-phase AC supply, with a rated output current of 40 A.
Key Features
- 3-phase AC input: Supply voltage: 400 V to 500 V rated; wide range input from 320 V to 575 V. Line frequency: 47 … 63 Hz.
- 24 V DC output: Rated output: 24 V DC and 40 A. Adjustable output voltage: 24 … 28.8 V via potentiometer; maximum 960 W.
- Output protection and diagnostics: The output is short-circuit proof. Protection uses an approximately 44 A constant-current characteristic or latching shutdown; green, yellow and red LEDs indicate 24 V OK, overload and latching shutdown.
- Galvanic isolation and protection: The input and output have galvanic isolation. Output voltage is SELV, ES1 (IEC 62368-1), DVC As (IEC 61204-7); protection class is IP20.
- DIN-rail installation: The enclosure measures 150 × 125 × 150 mm and snaps onto DIN rail EN 60715 35×15. Required spacing is 50 mm above and below, and 0 mm left and right.
- Screw terminals: Input terminals L1, L2, L3 and PE each accept 0.2 … 4 mm2 conductors. Output terminals + and – each have 2 screw terminals for 0.33 … 10 mm2.
