Voltage regulator Volter СНПТО-4р

Relay voltage regulator Volter SNPTO-4p

Relay stabilizer provides:

- stabilizing the output voltage level of 220 V with an accuracy of ± 10% when the input voltage of 145 to 285V, frequency 50 ± 2.5Hz;
- work throughout the range of loads from no-load to maximum load;
- protection tripping consumers with increasing input voltage over 285 V, followed by automatic connection load while reducing an input voltage to an operating level;
- protection tripping consumers when voltage drops of less than 130, followed by automatic switching loads with increasing input voltage to an operating level;
- protection against short circuit and overload long outlet;
- mode "transit "emergency;
- protection of consumers overvoltage in the" transit "with increasing input voltage 250 in connection with automatic load with a decrease in input second voltage less than 240 V;
- protection tripping in "transit" mode with a decrease in input voltage less than 140 V, followed by automatic switching loads with increasing input voltages greater than 150 V;
- protection of consumers from the output of overvoltage mode "stabilization»;
- thermal protection of the autotransformer in the temperature range 75-98 ° C;
- normalized (4.5-7.5 c) disabling customers at short mains failure (no damage pulsed sources power consumers);
- response time on a change of the input voltage is 30 ms
