一、产品介绍
HAVD系列晃电继电器用于***重要电动机在电源故障情况下能顺利自启动。
当电机有失电时，在0-10s(可调)时间内，输出接点保持闭合状态，若故障为晃电，则恢复供电后通过
由本接点构成的自保持回路，电机重新启动;如故障为***性故障，则接点延时断开。(适用于交流50/60Hz)
HAvD series of anti voltage drop relays are used to ensure the successful startup of electrical motorsby itself in case of power failure.
When power drops out in an electrical motor, with in 0-10s (adjustable), the output contacts remainclosed.In case of interruption of power supply, the electrical motor restarts by itself as soon as thesupply is resumed through the self-held loop composed of the contacts in the relays.If the failure ispermanent, the break of contacts will be delayed. (Are used in AC 50/60Hz)

“晃电”允许时间Tm AllowableTimeforInterruption of Power:0~10s
额定电压NominalVoltage:220VAC±10%
时间调整级差Gradation ofTime Adjustment:1s
触点容量Contact Capacity:在电压不大于250V时:触点长期接通电流为5A;在电压不大于250V时:电路时间常数L/R为5mS的直
流电路中，触点断开容量为50W;在电压不大于250V时:功率因数COS6为0.4的交流电路中，触点断开容量为250VA。
When the voltage is less than 250V,the continuous current o f the contacts is 5A; When the voltage is less than 250Vandtime constant L/R is 5mS in the DC circuit, the switching capacity of the contacts is 50W;When the voltage is lessthan 250Vand the power factor COSgis 0.4in the AC circuit, the switching capacity of the contacts is 250VA.
