Don't operate your backup or alternative electric power system blind, risking damage to your generator and/or appliances! Install this meter so you can see everything that is happening. Perfect for monitoring generator parameters when your transfer switch or panel does not have meters. The Amp scale will show if you are overloading the generator and the voltage and frequency scales can be used to verify the generator is operating properly. Selector switch included so that you can directly read the total generator load and also display the load on each hot leg.
COMBINED DIGITAL LED 3 BAR METER WITH SELECTOR SWITCH
- 3-IN-ONE METER (V, A, Hz)
- ANALOG READING, DIGITAL ACCURACY
- EASY TO SEE EVEN IN THE DARKNESS OF A POWER OUTAGE
- SELECTOR SWITCH TO INDIVIDUALLY READ L1 AND L2 OR THE TOTAL LOAD
- PRE-WIRED AND INSTALLED IN 3-GANG BOX FOR EASY WALL MOUNTING
- INCLUDES 3-GANG STEEL BOX, PRE-PUNCHED STAINLESS STEEL WALL PLATE, 18" ENT CONDUIT AND FITTINGS
- (2) CURRENT TRANSFORMERS OF PROPER RATIO FOR SEPARATE MOUNTING ON GENERATOR CABLES
This new line of instruments is designed as a cost effective alternative to the traditional separate analog panel meters and can replace up to four meters. An electronic solid-state design ensures maximum durability against vibration while a microprocessor based digital sampling technology provides maximum accuracy and stability in a wide range of environments.
Intuitive analog-style reading. Each parameter is displayed in analog format by high-luminosity color LED bar consisting of 10 dots. Voltage and frequency are displayed in real values. A central green reference dot adds further visibility to reading. Current is displayed in percent of full scale value to provide a quick indication of load condition.
Overload on each parameter is indicated by a "wrap around" flashing of the last three dots proportional to the overload value. A low signal on each parameter is also displayed by flashing the initial dot. The metering window is therefore effectively 4 dots wider than the 10 dots available.
This meter can help you prevent costly problems such as:
- generator damage due to inadvertent overloading beyond total rated capacity
- winding overheating and damage due to one leg overloading above 50%
- failure of motor-operated appliances from low frequency (due to engine governor problems)
- failure of expensive entertainment systems from high voltage (due to generator voltage regulator problems)
- failure of computers from high voltage (due to generator voltage regulator problems)
Here is one user's review of this meter without switch and installation kit along with pictures.
Voltage rating: 240V nominal, 215-275V display plus over/under voltage Frequency rating: 60Hz nominal, 55-66Hz display Current rating: 5A full scale for use with
external current transformers (CT)
0-100% plus overload
Equivalent power at full scale:
(use the generator's rated running load,
not the surge rating)
3.0-6.6kW with 50/5 CT
6.6-7.8kW with 60/5 CT
7.8-9.6kW with 75/5 CT
9.6-11.4kW with 90/5 CT
11.4-13.2kW with 100/5 CT
13.8-16.2kW with 125/5 CT
16.8-21kW with 150/5 CT
21-27kW with 200/5 CT
27-33kW with 250/5 CT
Design: microprocessor technology Accuracy: 0.5% on each dot Response time: 4 readings/sec Power consumption: 25mA (derived from voltage input) Operating temperature range: -10C to +50C Meter Front panel dimensions: 2.76"W x 2.36"H Meter Depth behind wall plate: 2.27" Mounting: standard 3-gang 3-1/2" deep wiring box Meter 5A Current input: integral donut sensor, 0.40" dia window Connections (all in 18" of ENT conduit): (2) hot wires for generator voltage
(2) pairs of wires for external CT
For exactly matching the 100% load scale on the meter we provide instructions for adjusting the CT ratios in the field by passing the secondary wire through the opening.
Meter is Made in Italy.
Detailed assembly instructions provided if you want to save money and do the assembly yourself. With some wiring experience and the proper tools this can be assembled in under 2 hours.
