4.1.2 Maximum Steady State AC and DC Currents
The power cable must be selected according to the current and voltage values in Table 4.1 below as well as the local wiring
regulations, and take environmental conditions (temperature and physical media) into consideration, then refer to Table 3B
in IEC 60950-1.

Note:
1. Max. current of low voltage (176 V) for rectifier input at full load.
2. Non-linear load (like switch power) affects the design of output and bypass neutral line.
3. The discharge current at EOD point (voltage is 9.6 V) calculated by 30-block battery.
