- Notes:[1)] _I_ P M is the highest peak level of the primary signal that is taken into account for accurate true RMS calculation. Yet the device is designed for maximum continuous true RMS value equal to _I_ P N, whereas the output is limited by the above specified output limitation
- 2) According to the UL 508 Standard for Safety for Industrial Control Equipment, the supply voltage must not exceed 42 V DC
- 3) Deviation of the offset during the test IEC 61000-4-3 between 100 MHz and 1000 MHz
## _I_ **= 100 ... 400 A** P N
## **Features**
- ●VFD and SCR waveforms current measurement
- ●True RMS output
- _I_ out = 4 ... 20 mA
- ●Panel mounting
- ●Eliminates insertion loss
- ●Insulating plastic case recognized according to UL 94-V0.
## **Advantages**
- ●Large aperture for cable up to ⌀ 32 mm
- ●High insulation between primary and secondary circuits
- ●Easy installation.
## **Applications**
- **VFD Controlled Loads**
- VFD output indicates how the motor and attached load are operating
- **SCR Controlled Loads** Acurate measurement of phase angle fired or burst fired (time proportioned) SCRs. Current measurement gives faster response than temperature measurement
- **Switching Power Supplies and Electronic Ballasts** True RMS sensing is the most accurate way to measure power supply or ballast input power.
## **Application Domain**
- ●Energy and Automation.
- 4) Deviation of the offset during the test IEC 61000-4-6 between 150 kHz and 80 MHz.

## **Current Transducer DHR-C420**
## **Safety**
This transducer must be used in limited-energy secondary circuits according to IEC 61010-1.
This transducer must be used in electric/electronic equipment with respect to applicable standards and safety requirements in accordance with the manufacturer’s operating instructions.
Caution, risk of electrical shock
When operating the transducer, certain parts of the module can carry hazardous voltage (eg. primary busbar, power supply).
Ignoring this warning can lead to injury and/or cause serious damage. This transducer is a build-in device, whose conducting parts must be inaccessible after installation. A protective housing or additional shield could be used. Main supply must be able to be disconnected.
