Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your particular application.
Hazardous voltages may be present when covers are removed. Qualified personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above WARNING (below) chassis ground.
The equipment used contains ESD sensitive ports. When installing equipment, follow ESD Safety Procedures. Electrostatic discharges might
WARNING cause damage to the equipment.
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform installation and servicing.
Ensure that the AC power line ground is connected properly to the Power Rack input connector or chassis. Similarly, other power ground lines including those to application and maintenance equipment must be grounded properly for both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO HUMAN SAFETY may be normally generated on the output terminals. The customer/user must ensure that the output power lines are labeled properly as to the safety hazards and that any inadvertent contact with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety glasses during open cover checks to avoid personal injury by any sudden component failure.
Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary sales organizations can accept any responsibility for personnel, material or inconsequential injury, loss or damage that results from improper use of the equipment and accessories.

SECTION 1
INTRODUCTION
Elgar's ContinuousWave™ (CW) Series power sources deliver up to 1250
VA in a 2U high (3.5 inches) rackmount chassis, and 2500 VA in a 5.25 inch chassis. This low profile design is also suitable for benchtop use. The CW Series models have three power ratings: 800 VA, 1250 VA, and 2500 VA. The switchmode, Power Factor Corrected (PFC) design efficiently delivers clean AC power.
Voltage, current, and frequency settings are quickly adjusted from the front panel knobs (10–turn potentiometers). Also, the sources can be programmed remotely from the rear panel analog port. The output is protected against overvoltage, overcurrent, and overtemperature conditions. They can be easily paralleled in the field with an additional parallel cable. A two-speed fan results in quieter operation at lower power levels.
Key features of the CW Series AC power sources include:High performance/value design
Output available at front or rear panel
Full rated current for two output voltage ranges: 0 to 135 VAC and 0 to 270 VAC
Low profile 2U (3.5") rack height for CW 801M and CW 1251M, and 5.25" rack height for CW 2501M
Single phase AC output: 45 to 500 Hz
Multi phase and paralleling
Measures output voltage, current, and frequency
Side air intake, exhaust to rear
Two large 4-digit, 7-segment LED displays
