Description
GZV-4000: The DIAMOND switching power supply is a 40A high power switching power supply but of reduced size and weight. It was designed and built specifically for powering transceiver equipment by providing a variable voltage between 5 and 15 Vdc. It is equipped with protection circuits: in current, which intervenes in the event of overloads beyond the limit value including short circuit, in temperature to prevent overheating which could damage the power supply.
An indicator, located on the front of the power supply, signals when the protection circuits have activated. Furthermore, given the use to which it is dedicated, it has a particular protection circuit against radio frequency interference (RFI). The analog instrument displays the voltage or current supplied, which can be selected from the selector on the front.
It has 3 DC power outputs: one at the rear with high power 40A sockets, while two outputs – one with 6A SNAP-ON terminals and one with a cigarette lighter socket – are hidden at the front under a removable panel. There is also an 8W and 8hm impedance front speaker that can be connected to the transceiver via a 3.5mm jack socket.
