  • Description

These Elgar CW1251M units are in good to above average condition. They work fine and have been load tested. The units are capable of producing 1250VA of power in low range to 135Vrms and 9.3 amps or high range at  270 Vrms with 4.62 amps.  These units are functionally sound but the voltage set and readback may be slightly off from actual output voltage measured with an external DMM. This can be remedied by standard NIST calibration/alignment by the factory at your discression. Cosmetically they are all about 82 to 92 on a scale of 100.  These units were originally  modified  (-111 option). We removed the modification and refurbished to standard design. We have many of CW1251M-111 modified to CW1251M units currently in stock. For a 90 day Warranty we will add $400.00 after Ebay purchase! Additional warranty is only available for full price purchases. Any discounts or Best Offers will negate the extended warranty offer.

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 1000 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 Continuous Wave (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
