Static current relay
Static current relay (JL-8GB / 1)
Static current relay is used to judge the overload of power equipment such as generators, transformers and transmission lines.
Load and short circuit protection.
Low current relays are used as blocking elements for PT disconnection.
It can completely solve the contact vibration and rejection when the electromagnetic relay is running, and the setting accuracy is not high.
The defect that the return coefficient is affected by the remanence can replace the DL-31, DL-32 electromagnetic relay.
The specific characteristics are as follows:
1. Convenient setting. The three-position dial switch is intuitive and convenient to set up without calibration.
2. The auxiliary power supply uses a switching power supply mode, AC and DC are universal, and the range is large.
AC 80V ~ 260V, DC 100V ~ 300V.
3. High accuracy, small current level difference: 0.1A, 0.01A, 0.001A and 0.1mA.
4, high reliability, no jitter, no rejection, fast action, high return coefficient.
It can be installed on the guide rail and fixedly installed, which greatly facilitates the customer's space, cost and installation time.
