概要（Overview）

The standard system cabinet contains the 4072A/4073A tester system instruments and is 1.6 m (5.3 ft.) high. The standard cabinet has an emergency off (EMO) unit. The 4072A/4073A tester requires single phase power configuration with protective earth. Its line voltage is 200, 208, 220, or 240 Vac, and line frequency is 50 or 60 Hz. The line voltage and frequency are selected by specifying options. The system cabinet for the 4072A/4073A tester is equipped with a power distribution unit (PDU) for each line voltage. The rated current of the PDU is 20 A for 200/220/240 Vac, and 24 A for 208 Vac. The short circuit current rating is 5 kA for 200/220/240 Vac, and 10 kA for 208 Vac.
