Features
Applications
The ContinousWave (CW) is designed for testing single or polyphase electronics.
The CW is well suited for applications requiring a cost-effective low profile AC source.
Applications include:
- Testing for real world sine wave power conditions
- 400 Hz testing for avionics equipment
- 50/60 Hz margin testing
- Ballast testing
- Components testing
- Power supply testing for AC to DC converters
Programmable CW Features And Benefits
Front panel encoder knobs allow programming of voltage, current and frequency settings. Programmed or measured values can be viewed on the two LED displays through push button selection. Menu push buttons enable setting system configuration including parallel or three phase operation. This menu also allows setting current shutdown or foldback modes. Remote IEEE-488.2 and RS-232 control interfaces are standard. LEDs indicate: high or low range output voltage, measure or program mode, voltage or current mode operation
and output-on. LED’s indicate menu/status, remote control, lockout and fault conditions. Digital Signal Processing (DSP) based measurements include voltage, current (amperes, peak amperes, crest factor), power (watts, VA and power factor) and frequency.
