| 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 |
