Product Overview

RENT Sorensen SGI250-120 


The Sorensen SGI250-120  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 SGI250-120 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 SGI250-120 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 SGI250-120.

Features of the Sorensen SGI250-120 include:

  • High Power Density: 30kW in a 6U chassis
  • Wide Voltage Range: 0-250Vand 0-120 Amps
  • Fast Load Transient Response: Protection from undesired voltage excursions
  • Low RMS and P-P Noise: Suitable for the most sensitive applications
  • Parallelable up to 150 kW: Expandable as your requirement grows
  • Modular Design: Upgradeable for the ultimate in investment protection
  • Sequencing: Program custom waveforms
  • Easy-to-read Fluorescent Display: Supports English, French, German, Italian, Spanish, Chinese, Japanese, and Korean languages
  • 16-bit Resolution: Optional IEEE-488.2 + RS-232C + Ethernet provides precise control
  • Ethernet Control: LXI Class C compliant communication through integrated web server
  • Direct Relay Control: Control output and sense isolation relays, along with polarity relays. (Ethernet Option Only)
  • Hardware Trigger: Ethernet Option Only 

Specifications of the Sorensen SGI250-120 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)

Environmental:

  • Operating Temperature: 0 to 50º C
  • Storage Temperature: -25º C to 65º C
  • Humidity Range: Relative humidity up to 95% non-condensing, 0º C – 50º C
  • Altitude: Operating full power available up to 5,000 ft. (~1,500 m), derate 10% of full power for every 1,000 feet higher; non-operating to 40,000 ft. (~12,000 m)
  • Cooling: Front and side air inlet, rear exhaust. Temperature controlled, variable speed fans. Units may be stacked without spacing.
  • Regulatory: Certified to UL/CSA 61010 and IEC/EN 61010-1, CE Compliant, Semi-F47 Compliant
  • Front Panel Dust Filter: 30 PPI (Pores Per Inch) - must ensure adequate airflow and / or derate max. temperature. 3U unit only.

Physical:

  • Dimensions: Width: 19.00” (48.3 cm), Depth 25.0” (63.5 cm) Height: 5-15 kW units: 3U – 5.25” rack mount (13.34 cm) 20-30 kW units: 6U – 10.5” rack mount (26.67 cm)
  • Weight: 3U < 80 lbs. (36 kg) 6U

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 Regulation (with sense wires used): no load to full load, nominal AC input); Voltage Mode: +/- 0.02% of full scale; and Current Mode: +/- 0.1% 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.
