Specifications

Options Purpose
Input Power: 200-240 VAC (±5%), 3-phase 22 amps, 50 or 60 Hz, 3-wire plus ground
Output Power: 0-230 VDC, 0-30 amps, current controlled.
Dimensions: 12.75" (plus two 1" mounting flanges) x 5" x 10.5", 32.4 cm (plus two 2.5 cm mounting flanges) x 12.7 x 26.7 cm
Weight: 19 lbs. (8.6 kg)
Options: 5 or 30 mA GFCI
Dual 4-20 mA input
Warranty: 2 Years
Input Power: 200-380 (±5%) VAC, 3-phase, 22 amps at 200 VAC, 11 amps at 400 VAC, 50 or 60 Hz, 3-wire plus ground
Line Filtering: Integral line filter meets CE conducted emissions requirement
Rated Capacity: 6.9 kW
Output Current: 0-30 amps
Output Voltage: 0-230 VDC
Output Current Control Range: Maximum output current (IMAX) is dipswitch adjustable from 6 to 30A.
Output Voltage Limit: Maximum output voltage (VMAX) is dipswitch adjustable from 14 to 230 VDC.
Non-isolated Output: The power supply output is not isolated from the AC input. The output must not be connected to secondary referenced circuitry.  Input voltage must be disconnected to prevent hazardous potentials from appearing at the output. DC control and logic circuits are isolated from the AC line and DC output.
Voltage Ripple: <2.5 volts for 0-50 VDC; <5% for 50-220 VDC
Regulation: <5% of actual output current
Control Band Width: The current control loop bandwidth varies with the load resistance (RLOAD) by the following relationship: Bandwidth = 5288/RLOAD (HZ)
Transient Response: Output current will regulate within 10 milliseconds of a setpoint change or load transient of up to 50%
Operating Temperature: 0-40 °C, no derating
Operating Humidity: 0-80% relative humidity, non-condensing
Cooling: External 4.69" fan (provided).  Leave >1" clearance around air intake and exhaust.
Control Signals: Output current proportional to 0-5 VDC input signal (0 VDC = 0 amps, 5 VDC = IMAX); current polarity reversed via TTL signal, On/Off via TTL signal.
Optional Control Signals: Dual 4-20 mA.  Normal polarity (cooling) output current proportional to input 1, reverse polarity (heating) output current proportional to input 2.  4 mA = 0 amps, 20 mA = IMAX
Fault Signal: A TTL high signal indicates normal operation. If a thermal shutdown or output stage overload occurs, a TTL signal low is produced.
Local/Remote Operation: Output current and polarity may be controlled via one of two sources: "remote" or "local"
Remote Sensing: A 0-5 VDC signal proportional to the output current at Imax/5 amps per volt, where Imax is the maximum output current setting
Over-current Protection: Automatic electronic current limiting is provided
Thermal Protection: Automatic shutdown when heat sink reaches 70 °C; automatic restart at 53 °C
Isolation: Can withstand a 3000 VDC Hipot with input and output terminals tied together
Courtesy Outputs: 12 VDC, 150 milliamps; 5 VDC, 20 milliamps
