Type 78.51 Switch mode power supply, low profile, high efficiency, with 12 V DC output at 50 W for electrical panels. Features include an adjustable voltage between 12 and 15 V and ZVS technology, and can be used as a battery charger. Overload limiting provides for battery charging and parallel connection for higher load currents-
Features include:
High efficiency (up to 91%)
Low consumption in stand-by (<0.4 W)
Internal thermal protection, with output shutdown
Short circuit protection: Hiccup mode (automatic reset)
Overload protection: Fold-back mode
Input fuse: Easily replaceable, with spare immediately to hand
Overvoltage protection: Varistor
Flyback circuit technology
ZVS (Zero-voltage-switch
ing) quasi-resonant technology
EN 60950-1 and EN 61204-3 compliant
Parallel connection for greater load current (with OR diode)
Dual polarity and serial connection possible
Small size: 70 mm (4 modules) wide, 60 mm deep
35 mm rail (EN 60715) mounting
