AMETEK Programmable Power announced an expansion of its popular Sorensen SG Series DC Power Sources to include a 50V model. Output voltages now range from 0-10VDC to 0-800VDC, currents up to 2400A, and power up to 150kW. With the recent expansion there are now over 100 different models for each of two separate versions (SGA and SGI) in the series. This extensive variety allows the user to better optimize voltage and current for their application resulting in the lowest cost for a specific application. In addition, the standard SG models provide slew rates typically 2.5X as fast and ripple 50 percent lower than competitive models. In some cases, SG models provide slew rates an order of magnitude better. The exceptionally fast load transient response, low noise, and ease-of-use across the SG Series accounts for one of the largest installed bases in the industry. In addition, the air-cooled SG units are high reliability power supplies that come with a five-year warranty.
Expansion of the Sorensen SG Series has reduced the cost of ownership for many applications. Users can choose a model with an output voltage, current and power combination best tailored to their needs, resulting in the optimum price/performance ratio. For example, the new 0-50V model provides an output of up to 100A at 5kW in a single unit. That allows the user to avoid jumping to 10kW 60V when their application only needs 5kW of power at 50V.
The SGA version comes with industry leading price/performance characteristics and is designed for users that most often use simple front panel analog controls or a remote serial interface. Features include 10-turn potentiometers for setting voltage and current, a 3½-digit LED readout, front panel over-voltage protection (OVP) preview/adjustment and reset, and multiple remote interface options.
The SGI version provides advanced onboard intelligent controls that enable sophisticated sequencing, constant power mode and save/recall of instrument settings. Looping of sequences makes the SGI 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 SGI.
Both versions have a load transient response that recovers within 1ms to ±0.75% of full-scale of steady state output for a 50%-to-100% or 100%-to-50% load change. Ripple and noise are as low as 20mv rms at full load (which depends on specific model and test conditions). Power factor correction (PFC) of 0.90 comes standard in the 50V, 30V and below models. PFC is available as an option in all other models.
With prices starting at $4454.00, most SG Series units are available four weeks after receipt of order.
