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:
<ul>
<li>High efficiency (up to 91%)</li>
<li>Low consumption in stand-by (&lt;0.4 W)</li>
<li>Internal thermal protection, with output shutdown</li>
<li>Short circuit protection: Hiccup mode (automatic reset)</li>
<li>Overload protection: Fold-back mode</li>
<li>Input fuse: Easily replaceable, with spare immediately to hand</li>
<li>Overvoltage protection: Varistor</li>
<li>Flyback circuit technology</li>
<li>ZVS (Zero-voltage-switching) quasi-resonant technology</li>
<li>EN 60950-1 and EN 61204-3 compliant</li>
<li>Parallel connection for greater load current (with OR diode)</li>
<li>Dual polarity and serial connection possible</li>
