For AC and DC signals
• AC + DC RMS measurements: DC to 440 Hz
PWM, phase angle modulation, wave trains, signals with high harmonic content
• Multi-sensor current input:
shunt, transformer, Rogowski coil, Hall effect sensor or direct input 1A and 5A
• Programmable: voltmeter, ammeter, frequency meter
• 4-digit measurement display for U, I, Hz
• 2 isolated analog outputs for simultaneous voltage and current transducers
• 3 relay outputs
• Ethernet connection with Modbus-TCP and SNMP
• Wide-range universal AC/DC power supply

The CPL35L is a programmable voltage and current measurement converter. Its various output options—
—enable a wide range of applications, including measurement, protection, and control. The second analog output allows
to simultaneously measure voltage and current in a fully isolated manner.

• Measurement of sinusoidal alternating signals (voltage or current)

• Direct input up to 250A and 1000V
• Galvanic isolation (up to 5000V)
• Accuracy: +/- 0.5%
• CAL45CA: measures 5A AC/DC; 500V AC/DC
• CAL45CAD: measures up to 50A AC; 1000Vac

The CAL45CA family of measurement converters converts AC voltages or currents (
) into a 4–20 mA current proportional to the input value. The use of 2-wire technology (
, where the converter is powered by the 4–20 mA loop) simplifies wiring.

• DC input from 1 A to 100 A (or ±1 A to ±100 A)
; bandwidth up to 50 kHz

• Hall-effect technology with 25 mm² screw terminal input (5 A to 100 A max.)

• Single- or dual-pole current or voltage output: 0–4–20 mA, ±20 mA, ±10 V,
, isolated from the power supply

• Direct shunt replacement possible Isolated mV output (no heat dissipation)

Power supply
: 4.5–18 Vdc, 18–36 Vdc, 9–36 Vdc, 18–75 Vdc, …

The CAL35CC transmitter measures DC current up to 100 amps, serving as an effective replacement for measuring shunts by reducing insertion losses and providing a conditioned signal (4–20 mA, 0–10 V, or mV). The open-frame version is particularly suitable for retrofitting existing installations and even allows for installation without shutting down the system.
Applications: solar farms, wind farms, batteries, industry
– detection of defective panels
– measurement of power output from each panel
– control of panel orientation
– battery monitoring, DC motor monitoring
– welding

• CAL35CAD
Measurement of sinusoidal AC signals

• CAL35CAD-RMS (true RMS version)
, PWM, phase angle modulation,
,
, and all signals with high harmonic content

• Built-in through-hole Ti option rated up to 50Aac

The CAL35CAD measures AC voltage or current and converts it into a standardized analog signal (0 … 4 … 20 mA or 0–10 V) proportional to the rms value of the input signal.
Using the built-in current-sensing transformer (optional) allows for direct measurement without an external transformer.

Measurement converter for 50 Hz, 60 Hz, and 400 Hz sinusoidal AC signals (voltage or current) (
)

• CAL35CA/A version powered by the measurement signal
