Product Overview

The Sorensen SGI600-33  is a Programmable Precision High Power DC Power Supply that is designed for exceptional load transient response, low noise and high power density which is enhanced by a stylish front air intake allowing supplies to be stacked without any required clearance between units. The SGI600-33 combines onboard intelligent controls with outstanding power electronics. These controls enable sophisticated sequencing, constant power mode and save/recall of instrument settings. Looping of sequences makes the SGI600-33 ideal for repetitive testing. An impressive vacuum fluorescent graphical display in eight languages, context sensitive “soft” keys and front panel keyboard simplify programming of the SGI600-33.

Specifications of the Sorensen SGI600-33 include:

Common:

• Remote Sense: Load-line loss compensation for models <= 100 V is 10% above full scale voltage total (5% per load-line), and models > 100 V is 4% above full scale voltage total (2% per load-line).
• 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 (see Output Float Voltage)

Input:

• Nominal Voltage 3 phase, 3 wire + ground: 208/220 VAC (operating range 187 - 242 VAC); 380/400 VAC (operating range 342 - 440 VAC); and 440/480 VAC (operating range 396 - 528 VAC)
• Frequency: 47 – 63Hz (optional 400Hz @ 208VAC, does not carry CE, UL or CSA markings)
• Power Factor: >0.9 typical at 208/220 VAC input; >0.78 typical at 380/400 VAC input; and  >0.69 typical at 440/480 VAC input
• Protection (typical): ½ cycle ride-though on all three phases, 3 cycle ride through on single phase; missing phase shutdown (800V model 6.4 msec on all 3 phases)

Output:

• Ripple & Noise (Voltage Mode, Typical): Ripple and noise specified at full load, nominal AC input. Noise measured with 6ft. cable, 1µf at load
• Ripple (Current Mode): <+/- 0.04% of full scale rms current
• DC Voltage Slew Rate: 45A / ms typical - resistive load
• Line Regulation (with sense wires used): (±10% of nominal AC input, constant load); Voltage Mode: +/- 0.01% of full scale; and Current Mode: +/- 0.05% of full scale

• Load Transient Response: Recovers within 1ms to +/-0.75% of full-scale of steadystate output for a 50% to 100% or 100% to 50% load change
• Efficiency: 87% typical at nominal line and max load
• Stability: ±0.05% of set point after 30 minute warm-up and over 8 hours at fixed line, load and temperature
• Temperature Coefficient: 0.02%/ C of maximum output voltage rating for voltage set point 0.03%/ C of maximum output current rating for current set point
• Output Float Voltage: Negative terminal within +/- 300 V of chassis potential. (We recommend the use of optional isolated analog Interface (IAI).) Supplies in “series” should be the same output voltage/current.
