Product Description
. . . . . Yokogawa 254220RXRX Current and Voltage Monitoring Panel Meter, DC Volts 0-LEFT,0-300 D-C Volts
Rating- 0-300 V/DC
Scale- 0-300
Legend- DC VOLTS
SPECIFICATIONS:
Accuracy: All DC and AC iron-vane; +-2% of full-scale AC rectifier type; +-3% of full scale (with 60 Hz sine wave at 25 degrees C). When standard 60 Hz iron vane ammeters are used at the extreme limits of 25 or 400 Hz, additional error (approx. .75%) may be experienced. Expanded-scale voltmeters: +-.5% of full scale value.
ANSI Specification: All meters meet ANSI Specifications C-39.1
Overload: Voltmeters (AC and DC) - 50% momentary, 20% sustained. Ammeters (AC and DC) momentary; 10 times the rated current for 10 consecutive intervals of .5 second with a 1 minute interval between successive applications; sustained: 20% for six hours.
Scale Data: 90 degree rotation.
Scale Length:
1.40in on the 1-1/2in model
2.06in on the 2-1/2in model
2.88in on the 3-1/2in model
3.93in on the 4-1/2in model
Insulation Level: All meters (except 1-1/2in), 2600 Vrms Hi-pot, 1-1/2in-1500 Vrms Hi-pot.
Burden Data: AC ammeter-5 amps, 0.5 va, Max. 0.5 power-factor lagging at 60 Hz. AC voltmeter - unity power factor.
Response Time: 3 seconds (max.) for 2-1/2in, 3-1/2in, 4-1/2in size for microammeters; 2 seconds (max.) for all other DC ratings, and 2.5 seconds (max) for AC ratings.
Overshoot: Maximum of 40% overshoot.. Yokogawa. Yokogawa. 254220RXRX.
