产品资料：
interruption occurs on the side where power supply exists from the
point of connection, and interruption on the loading side cannot be
detected.
7. This product cannot be used for thyristor controls or inverters.
8. There is a risk of internal circuit breakage by high frequency
waves. Don't use the product at the load side of inverter.
Ideal for monitoring 3-phase power supplies
for industrial facilities and equipment.
• Monitor overvoltages, undervoltages, phase sequence, and
phase loss for three-phase 3-wire or 4-wire power supplies with
just one Unit.
Switch setting for 3-phase 3-wire or 3-phase 4-wire power
supply.
• Two SPDT output relays, 6 A at 250 VAC (resistive load).
Output overvoltages and undervoltages using separate relays.
• World-wide power specifications supported by one Unit
(switchable).
• Output status can be monitored using LED indicator.
