Protection Multimeter
Product Details
IEC 60974-2
IEC 62052 Class 2
Standards : IEC 61010-1
Weight: 320 gm.
Panel cut out: 90+1X 90+1 mm.
Dimensions: 96X96X71 mm.
Degree of protection: IP 40 (front panel)
Humidity: < 75% RH non-condensing.
Operating temperature:-5 ?/SUP>C : 55 ?/SUP>C
Mechanical Parameters:
Power consumption: < 1 watts.
Display: 3X3.5 digits (7 - segment,14 mm height- highly illuminated red display)
Sampling rate: 833k. Samples/sec. @ 50 Hz.
Power supply voltage: From 85-280 VAC (thanks to the well designed switch mode power supply)
a separate power supply.
Power supply : From the measured voltages ?no need for
Operating frequency: 45-65 HZ
Current measurement range: 50 mA ?6 A (i.e. from 1% to 120% of full scale)
Current transformer ratio: 5/5 to 2500/5
Current: 5-amp from external current transformer.
Volt measurement range 85-270 VPH
Voltage: 380 / 220 VAC
System : 3-phase, 4 wire unbalanced load.
Electrical Parameters:
Using a 500/5 current transformer ratio means the overload threshold can be adjusted from 100 amps. To 600 amps. !!
Example:
This substitutes the usage of the thermal overload relay to protect your load or motors. The contact is active if the adjustable OL limits are reached (from 20% to 120% of the full scale of the meter), and continue for a pre-defined time (toff), programmed from 1 sec. to 120 sec.
Applications:
- Enable/Disable Control function.
- Ton : Time of reconnecting the load after detection of normal utility from 1 to 120 sec.
- Toff: Time of disconnecting the load after detection of OV/UV from 1 to 120 sec .
- Over load threshold: (OL) adjusted from 20% to 120% of the full scale of the meter .
The following parameters can be set by the user:
- Phase rotation error protection.
- Phase loss protection.
- Over load protection
B. Control:
- Frequency
(VL1-N, VL2-N, VL3-N, VL1-L2, VL2-L3, VL3-L1)
- AC RMS values of 6 different voltages
