Application

Pulse power supplies are widely used as power sources for electrical current and voltage in radioelectronics, communication and computing, medical equipment, automatic control of production processes, as well as in other areas of electronics. They build up and stabilize the voltage that an electric appliance is powered by, while at the same time setting and adjusting the current impulse. A great advantage of the pulse power units is their compact size, as well as the high efficiency - over 90%.

More information

To properly select the power of the device, it is advisable to consult a specialist. The power must be based on the power of the consumers and the type of load:

The nominal power of the device must be 20-30% higher than the load capacity of the consumer at an active load (heaters, electric ovens, furnaces, stoves, incandescent lamps, etc.). This is due to the high starting current of the loads. When the load is switched on and during repeated short-time modes, the load over a short period significantly exceeds the nominal parameters specified in the load characteristics.

When the device is used in conjunction with inductive load consumers, the power must be 3 to 5 times the power consumption of the load! (fluorescent lighting, electric motors, pumps, air conditioners, refrigerators and freezers, etc.).

When the device is used for consumers with a capacitive load, the selected power must be 5 to 10 times greater than the power consumption of the load! (pulse chargers, LED drivers, pulse power supplies, etc.).

If these instructions are not complied with, it is possible for the device to be overloaded and stop functioning, and the warranty will not cover the damage.
