Toyo Keiki EVF-11M-RVF-11M Wattmeter and Varmeter Electronic Device Type Time Sharing Multiplication Method
Product Made In Japan
Manufacturer: Toyo Keiki
Model: EVF-11M-RVF-11M
Remarks
Using VT, CT
Use a combination of the 110V5A rating meter with VT and CT if the rating on the left is exceeded.
Measurement Range Value
Select the measurement range from the wattmeter measurement range selection standards chart on P15.
Production Limits of Meter
Usable Voltage Range
Rated voltage within ±15%
Varmeter Scale
The standard scale of a varmeter is LEAD ~0~LAG kvar. Note) Pulse meters(0~ kvar) are also producible.
(For pulse meters, designate LEAD or LAG.)
Meter Wiring
1. You cannot obtain a normal indicator if phase is reversed. Therefore, be sure to check the phase sequence of the bus and the polarity of VT and CT.
2. For phenomena related to mis-wiring, please contact. 1P3W Wattmeter
1P3W Wattmeters as listed on the left can be manufactured.
