Product category : Relays

Ashida electronics pvt. Ltd. Designs, develops & manufactures electrical power protection relays & scada systems. Numerical protection relays are based on dsp technology. Various protection functions are incorporated in that such as over current, under current, lbb, trip circuit, etc. The numerical voltage protection relays are dsp based `numerical` communicable/non-communicable voltage operated relays. They can be programmed for idmt or definite time operation. This voltage protection relay is a numerical inverse time under voltage relay with the following distinct features:

1. Adr112a has 1 phase inverse time under voltage protection with idmt time
2. 1 phase inverse time under voltage relay.
3. Programmable [non- volatile] setting by local keys back - lit lcd display for settings.
4. Display of fault voltage / load voltage.
5. Voltage sensing setting range - 30% to 90%.
6. Design using dsp technology.
7. Latching of fault value.
8. Pass-word protection for setting.
