Lightning and Surge ProtectionEnerProEP 12V-20A/LEDEP 24V-20A/LEDEP 36V-20A/LEDEP 48V-20A/LEDSPD for high operating current and high discharge capabilityProtection of low voltage high power DC or AC power supplies up to 20A• High performance surge protective device (SPD) for supply voltages of 12 V- 48V• Max. impulse discharge current of 40 kA (8/20 µs) acc. IEC 61643-1• High operating current possibility up to 20 A• Direct mounting on mounting plate, or snap on EN 50022 DIN rail• Maintenance free execution• Visual monitoring of operating voltage and SPD function by LEDProduct descriptionBecause of the high impulse discharge capacity (line-to-ground: 40 kA at 8/20 µs) of the EnerPro12V/24V/36V-20A/LED SPD and the comfortable and easy installation on 35mm DIN rail, this SPD can be universally used.It consists of a high reliable protective circuit between line and ground as well as between line and line, a visualfunction indicator by green LED. The operating voltage is indicated by a red LED. The SPD has safety disconnectioncontacts, which will respond if the MOV reach excessive leakage current due to overloading. Whenthis happens, the green LED will extinguish and the SPD must be replaced.ApplicationEnerPro12V/24V/36V/48V-20A/LED have been designed for the protection of AC and DC power supplies ofhighly sensitive electronic equipments, with high power consumption.To be installed at the boundary 1-2, according to the lightning zones concept of VDE 0185-305-1-4, (IEC 62305part 1-4).Protects People and Valuable
