Limiters of tension of idling ONT-3
Limiters of tension ONT-3 I am similar devices on the application from ONT-1. Its main difference is a work with the welding machines which are powered from a network of 3 phase tension ~ 380 V, 50 Hz.
Limiters of tension ONT-3 work together with one - or welding machines multion point duty and rectifiers for manual arc welding with supply voltage from a 3 phase electric network ~ 380 V, with a frequency of 50 Hz.
Limiters can be used in various branches of a national economy during welding works under a canopy or in rooms with ambient temperature from - 40 to +55 °C.
Devices have a high rate of reliability, convenient system of indication, are easy in operation.
At the low price, all these indicators give the grounds for increase in a consumer demand in the market of welding subject, as in the domestic market, and abroad.
