♦ Options Introduction 1.1 Brief Introduction The IT6000C series Bi-directional Programmable DC Power Supply supports a variety of output capabilities to satisfy different test requirement such as high current and low voltage or high voltage and low current. Meanwhile, units of the same model can be run in parallel to deliver stronger output capacity.
Page 14 When the Sense function is turned on, it can ensure that the DUT is safe in case of reverse connection or open circuit of the Sense line. The IT6000C series was designed to allow paralleling of multiple units to cre- ate larger power systems. Expandable in master and slave parallel Up to 1152kW.
Page 15 The current and power input capacity is same as the output capacity. For example, the maximum rated value of the output power of the IT6018C- 500-90 model is 18,000W, and the maximum rated value of input power is al- so 18,000W. Copyright © Itech Electronic Co., Ltd.
