-Alimentation and detection 85 to 139 V (50/60Hz)

-Protection : Fuses embeded in resin

Features:

- Storage : -55°C ; +85°C

- Operation : -40°C ; +65°C

- Voltage regulation: ± 0.5%.

- Voltage supply/sensing range 85 to 139 V (50/60 Hz)

- Rapid response time (500 ms) for a transient voltage variation amplitude of ± 20%
