| AC Input: |
The standard AC input is 460 VAC ± 10% 30 60 Hz. The supply will function within full specification from 440 to 480 VAC. Phase-to-phase balance requirements ± 2% is required for ripple specification but phase-to-phase rotation sequence of AC input is not required.
Current draw per phase: 20 kW per phase: 20kW units is 81A @ 208 VAC & 44A @ 440 VAC; 30 kW units is 123A @ 208 VAC & 62A @ 440 VAC; 60 kW units is 119 @ 440 VAC, 208 VAC not available for 60kW units. |
| Regulation: |
Effects of line and load variations (within the ratings of the supply) on output voltage or current are within 0.1%. Readings can be affected by output ripple which, by specifications, can exceed this rating. |
| Stability: |
Output voltage and current remain within ± 0.05% for 8 hours, with constant external effects. |
| Transient Response: |
Output variations, caused by line variations of 10%, and/or load variations between 50% & 100% of rated limits, will typically recover to within 1% of its final value within 200 MS. |
| Remote Sensing: |
Maintains regulation at load, compensating for IR drops in the power output leads. |
| Remote Programming: |
Resistance programming of either constant-voltage or constant-current modes. Units can also be programmed by an external reference voltage in either mode of operation |
