Voltage relay DY-20 seriesPrices, manufacturers, wholesale-Shanghai A Cheng Electric Co. Ltd.

Use

Dy - 20C, 20d series voltage relay (hereinafter referred to as the relay) for generator, transformer and transmission line voltage rise (overvoltage protection) or the voltage reduced (low voltage blocking) relay protection circuit.

The main technical parameters

Value:	Over voltage relay at 1.2 times the setting value, the action time is not more than 0.15s;
	Low voltage relay at 0.5 times the setting value, the action time is not more than 0.15s;
Contact form:	1, 1, 1 and 1 break break, 2, break 2.
Contact capacity:	No more than 250V voltage, the electric current does not exceed 5a, the time constant for 5 + 0.75ms DC sense circuit load, product output contact breaking capacity is 50W. The output contacts in the above specified load conditions, the product can act reliably and return 5 * 104 times. The output current is 5A connected to allow long-term contact.
Medium strength:	Products of each conductive terminal even together, on the exposed uncharged metal part or between the shell, bear 2000V (RMS) 50Hz AC voltage which lasted 1 minute test without dielectric breakdown or flashover phenomenon.
