Current sensor CSNP661
1. Description
The CSNP661 closed-loop current sensor is based on the principle of magnetic compensation. If the primary/secondary circuit is electrically insulated, DC, AC and pulse current can be measured.
2. Electrical parameters
Rated current (In): 50A.t rms (rated value)
Features
? Can measure AC, DC and pulse current
? Competitive price/performance ratio
? Better accuracy and linearity
? Fast response time
? High overload capacity
? High standard electrical insulation between primary and secondary circuits
? Industrial-grade operating temperature range
? Small size and light weight
Measuring range: 0~±90A.t(DC~AC Peak)
Measuring resistance (at 70℃): Rm min Rm max
with±15V, at±50 A.t Max: 70ohm 195ohm
Analog output current (at 50A): 50mA
Turn ratio: 1/1000
Accuracy (25℃): better than ±0.5%In
Power supply voltage: ±12~15VDC (±5%)
Original secondary side electrical insulation: 3KVrms/50KHz/1 minute
3. Accuracy-dynamic parameters
Zero offset current (25℃): better than ±0.20mA
typical application
? Variable speed drive equipment,
? servo motor
? UPS and telecommunications equipment power supply
? Power supply for welding equipment
? Automobile-battery management system
? Overcurrent protection
? Earth fault detector
? Robot
Offset current temperature drift (0~70℃): ±0.30mA (typical value)
: Better than ±0.50mA
Linearity: better than ±0.10%
Response time: better than 500ns
Bandwidth: DC~150KHz
dI/dT precise following: better than 100A/μs
4. Technical indicators
Operating temperature range: -40~85℃
Storage temperature range: -40~90℃
Current consumption: 10mA plus output current
Secondary coil resistance (+70℃): 30Ω
Sensor housing: Polycarbonate/ABS synthetic
Connection form (primary): perforated
Connection form (secondary): 3X0.8mm PCB solder pins
Notes
1. Higher resistance can be used when measuring lower range;
2. The above parameters are in the case of 25 degrees and +/-15V power supply, unless otherwise stated.
