This is the nominal value at 25 °C and applies to cold models at initial switch-on cycle. Subsequent switch-on/off cycles increase the inrush current peak value. 3 For 1 s max. 4 AC operating frequency range is 47 to 440 Hz (440 Hz for 115 V mains). For frequencies ≥ 63 Hz refer to Safety and Installation Instructions. Input Transient Protection A suppressor diode and/or a VDR (depending on input voltage range) together with the input fuse and a symmetrical input filter form an effective protection against high input transient voltages which typically occur in most installations, but especially in battery-driven mobile applications. Nominal battery voltages in use are: 12, 24, 36, 48, 60, 72, 110, and 220 V. In most cases each nominal value is specified in a tolerance of –30% to 25%. In certain applications, surges according to RIA 12 are specified in addition to those defined in IEC 60571-1. The power supply must not switch off during these surges and since their energy can practically not be absorbed an extremely wide input range is required. The EK input range for 110 V batteries has been designed and tested to meet this requirement. Electrical Input Data General Conditions – TA = 25 °C, unless TC is specified. – Pin 18 connected to pin 14, R input not connected, Vo adjusted to Vo nom (option P) – Sense line pins S+ and S– connected to Vo+ and Vo–, respectively.
