The DC power supply SP120VDC4000W
The APM SP-Series programmable DC sources from APM Technologies have an operating efficiency of up to 89%. A special measure in the circuit design of the switching architecture reduces possible damage to the component itself. As a result, the overall efficiency is increased and, at the same time, the rate of temperature rise of the DC power supply is decreased. When compared to other similar types of products in the market, APM Technologies sources offer significant advantages. Thanks to the unique fast-drop function, the response behaviour of the SP-Series is significantly better than that of comparable products on the market.
The sources have a built-in digital voltmeter (DVM) and this independent function can measure the value of the output voltage at the output terminal and display the value on the VFD screen by toggling the buttons on the front panel. The DC source can also be used as an external device for laboratory tests to measure voltage values. In the master-slave control mode, up to 4 APM units can be used in either a series or parallel mode. This control mode has the effect of “one hundred answers to one (single) call”. As soon as the mode is set, the “slave” is blocked in the main interface and controlled exclusively by the “master”. If a “slave” signals a problem with the protection mode,
