Options
 |
Increased Output Power | |
|---|---|---|
| The conservatively rated unit allows todeliver extra output power with the same reliability. At some derating,either the maximum output voltage or the maximum output current can be increased by about 10%. | ||
 |
Two-Quadrant Output: Power Sink | |
| Two quadrant operation maintains the output voltage constant regardless the output power is positive or negative. Ideal for PWM-speed controlled DC-motors and ATE-systems. | ||
 |
High Speed Programming | |
| A 10 to 20 times higher programming speed and lower output capacitance. Excellent for laser applications, test systems or as current source with low parallel capacitance as used in plasma chambers. | ||
 |
Digital Voltage and Current Setting | |
| Reliable, longlife digital encoders are implemented at the front panel. Includes total front panel lock (also for CV- / CC- knobs) and a coarse or fine pitch adjustment depending on the turning speed. | ||
 |
High Voltage Isolation (up to 1000 V) | |
| A higher output isolation allows series operation up to1000 V. | ||
 |
Front Power Output | |
| Bind posts at the front panel instead of at the rear panel. | ||
 |
Sequencer | |
| Arbitrary Waveform generator or standalone automation. The sequencer is integrated in the Ethernet controller. | ||
 |
Secured Voltage and Current Setting | |
| For maximum security, the CV / CC settings can be adjusted with a screwdriver only and are protected with a plastic cap from accidental adjusting. | ||
|
19 Inch Rack Mounting Adapter | |
| The 19 inch mounting adapters makes it possible to position one or two units side by side in a 19 inch rack. | ||
