Diamond GZV4000 – Switching Mode DC Power Supply 40 Amp


The GZV4000 Switching Mode DC Power Supply provides high power output with its small size and light weight. It is suitable for a variety of uses, especially for DC operated radio equipment source from an AC outlet and providing variable voltages of 5V to 15V and up to 40A continuous operation.


Lightweight and Small Size: The switching mode power supply has the advantages of being lightweight and small in size. Comparing with linear mode power that has the same power output, it is much lighter and smaller.

High Efficiency: The unit is operated with efficiency over 80%.

Overload Protection: The current foldback circuitry is designed to prevent from overload. The overload indicator will be lit up when the unit is overloaded. Overheating Protection The overheating circuitry is functioned when the unit reaches a certain high temperature to prevent the unit from damage. When the circuitry is functioned, the output voltage and current will drop down to a safe value and the overload indicator will light.

Insensitivity to RFI. Variable Voltage Output: The variable range of output voltages are from 5V to 15V.

Multiple DC Output Connections: The unit has a pair of 6A easy snap on output terminals, a pair of full power screw-on output terminals and a cigar-lighter type output jack.
