Purpose designed for lighting applications, this device overcomes problems that are usually found when using conventional or Hall effect CTs.
Used in conjunction with Voltech power analyzers, the ballast CT is a free-standing module that provides a convenient and accurate solution to lighting ballast power measurement.
Advantages
- Convenience: No need to feed cables through a CT core.
- High accuracy: Trifilar wound toroidal core design - no cable positioning/contact error
- Wide bandwidth: High frequency design provides 5kHz to 1MHz bandwidth
- Wide current range: 5mA to 1A - Measure many tube types with one device
- Safety: Electronic protection for overcurrent. Meets EN61010-1 safety standards
Specifications
- 5mA to 1A RMS current in two ranges
- 5kHz to 1MHz bandwidth
- Amplitude better than 1%
- Phase (current output) better than 1°
- Phase (voltage output) better than 3°
- Maximum voltage (ballast/tube to output) - 1000vpk
Measurement Examples
High Current
Using your power analyzer in conjunction with the current transformer, tube currents between 50mA and 10000mA may be measured.
Lower Currents
Where lower currents are flowing, the following configuration will allow readings between 5mA and 100mA.
Voltage output on the low current range increases sensitivity with low power tubes.
Two Tube Measurements
With two current transformers and a three phase Voltech analyzer, such as the PM300, ballast efficiency measurements are simple and accurate.
Low voltage lighting measurements
The benefits provided by the ballast CT of isolating the common mode switching voltages also apply to low voltage lighting systems.
