Function
The CTS split-core current transformer provides a safe, low-voltage output for accurate power and energy measurement. Its split-core design enables quick and easy installation without the need to disconnect the primary conductor. Shorting blocks are not required, as the CTS includes an internal secondary burden resistor. The 333 mV output signal ensures compatibility with DIRIS A-100/A-200 (333 mV models), WattNode power meters, and any third-party meter designed to accept 333 mV current sensor inputs.

Advantages
Safe Installation
- No need to disconnect existing wiring—just open the core and clamp it around the conductor.
- Built-in burden resistor provides 333mV.
- voltage output at the rated full-scale current, eliminating the need for shorting blocks.
Accurate
Low phase angle error ensures accurate current measurements, typically ±1% from 10% to 100% of rated current, essential for accurate power and energy measurements
Flexible & Compact Design
Small form factor allows for easy installation in tight electrical panels, and it supports low voltage (333mV) CTs.
Universal low voltage
333mV Output is compatible with most energy meters and monitoring equipment.
