 | Charging when connecting the supply voltage The EL2212 contains large capacitances for ensuring the high peak currents. The charging of the capacitances may therefore result in spark discharges at the contact points when connecting the supply voltage. It is recommended to connect the cables first before switching the power supply on (transformer, power supply unit). |
