Battery charger mode
ALPHA is delivered in battery charger mode as a factory setting. Output voltage is predefined for VLRA
batteries at 2.27 V per cell, or 13.6 V, 27.2 V, 54.5 V or 136.2 Vdc according to the model. When the desired
output voltage is different, i.e. when using a nickel-cadmium battery with 1.42 V per cell as a recommended float
voltage, it is possible to adjust output voltage by roughly ±5% using U potentiometer.
