| General Specifications |
| Remote Sense |
Terminals are provided to sense output voltage at point of load. Maximum line drop 5% of rated voltage per line for 40-100V models, line drop 1V of rated voltage per line for 10-20V models, 1.5V for 30V models, 2% of rated voltage per line for models 160V and greater. (Greater line drop is allowed, but output regulation specifications no longer apply). |
| Parallel Operation |
Up to 5 units may be paralleled for additional current within the power supply single-unit specifications, with exception of the DC output current set accuracy. Additional paralleled SG units will add 0.3% inaccuracy per unit. To parallel more than 5 units, contact factory. |
| Series Operation |
Up to 2 units |
| Input |
| Nominal Voltage: 3 phase, 3 wire + ground |
208/220 VAC (operating range 187 - 242 VAC)
380/400 VAC (operating range 342 - 440 VAC)
440/480 VAC (operating range 396 - 528 VAC) |
| Frequency |
47 – 63Hz , 400Hz ( 400Hz @ 208VAC, for 6U units is optional modification and does not carry CE, UL or CSA markings ) |
| Power Factor |
>0.9 typical for 10V - 30V, 50V, 1000V and other models with optional “PF” modification.
>0.75 typical for 208/220 VAC input (40V, 60V - 800V models, 0.9 available with modification “PF”)
>0.72 typical for 380/480 VAC input (40V, 60V - 800V models, 0.9 available with modification “PF”)
>0.69 typical for 440/480 VAC input (40V, 60V - 800V models, 0.9 available with modification “PF”) |
| Protection (typical) |
½ cycle ride-though, typical, on all three phases, 3 cycle ride through on single phase; missing phase shutdown (800V model 6.4 msec on all 3 phases) |
