800VA - 2500VA, Cost-effective Low Profile AC Source
Product Overview
The ContinuousWave (CW) Series of AC power sources provides clean single phase power at an impressive price/performance ratio. These compact switch mode sources come in two series, manual (CW-M) or programmable (CW-P) with standard IEEE-488.2 or RS-232 control. Both series have three power levels, 800 VA, 1250 VA and 2500 VA. The 800 and 1250 VA models are 2U (3.5") high and allow the unit under test to be connected to the front or rear panel. The 2500 VA model is 3U (5.25") high with rear panel output connections. All models can be operated in a benchtop or rackmount configuration.
The front panels have two bright four digit, seven segment displays. Power Factor Corrected (PFC) universal input voltage allows maximum power to be delivered from an AC outlet without the user selecting the range. Fully rated current is delivered for either output voltage range of 135 VAC or 270 VAC over a standard frequency range of 45 to 500 Hz. Both series can be paralleled to provide extra power. A separate output-on switch controls power to the load. Remote voltage sense is standard. Transformer coupled output is protected against overvoltage and overcurrent. The unit is also protected against over temperature conditions. A two-speed fan results in quieter operation at lower power levels. All models are CE marked.
Features And Benefits Key Features
• Wide range PFC Input
• Low THD and AC noise
• Advanced Measurement Available
• Field Parallel Configurable
• Multiple Units Configurable for Poly-Phase Operation
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
Manual CW Features And Benefits The manual series front panel knobs (10 turn potentiometers)
allow quick adjustment of voltage,
current and frequency settings. Frequency and
voltage can be programmed remotely using a 0 to
5V analog signal. LED’s indicate: output-on, voltage
or current mode operation, fault and slave modes.
Models can also be paralleled in the field or configured for three phase operation using a factory supplied
cable. Current shutdown or foldback modes
can be selected from a rear panel switch.
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.
