Longlife precision

The SM1500 Series consists of power supplies with excellent lifetime and stability. Multiple power supplies can be connected in series, parallel, or both in series and parallel to create numerous output configurations. Optionally, power sink can be ordered with this power supply to be able to dissipate up to 200W. 

Standard, the SM1500 can be controlled either via the front or an analog input at the rear of the power supply. Optionally, Ethernet, RS232 or isolated remote programming features can be factory installed. Furthermore, external interface modules are available to add this functionality to existing units.

 

cTUVus Certification

The SM1500 series is certified according to the UL 60950-1:2007 R12.11 standard. This certification by the reputable TÜV Rheinland is a confirmation of the high safety and quality standard of Delta Elektronika. This certificate combined with Delta Elektronika's reputation of long term product availability and product support turns the SM1500 series into excellent power supplies for larger systems.

Options

Optional factory installed features

High Speed Programming

High Speed Programming

A 10 to 20 times higher programming speed and lower output capacitance. Excellent for laser applications, fast test systems or as current source with low parallel capacitance as used in plasma chambers. For more information, download the data sheet High Speed Programming.

Digital Encoders

Digital Voltage and Current Setting

Reliable, long life digital encoders are implemented at the front panel. Includes total front panel lock and a coarse or fine pitch adjustment depending on the turning speed. For more information, download the data sheet Digital Encoders.

2-Quadrant Output: Power Sink

2-Quadrant Output: Power Sink

The 2-quadrant operation maintains the output voltage constant regardless the output power is positive or negative (for units up to max. 70 V only). Ideal for PWM-speed controlled DC-motors and ATE-systems. For more information, download the data sheet Power Sink.

Secured Voltage and Current Setting

Secured Voltage and Current Setting

For maximum security the settings for CV and CC can be adjusted with a screwdriver only and are protected with a plastic cap from accidental adjusting. Units with digital voltage and current setting already have secured settings.

Increased Output Power

Increased Output Power

For conservatively rated units, extra output power (with the same reliability) is allowed. At some derating, either the maximum output voltage or current of these units can be increased by about 10%. Contact us or our local distributor for information which units extra output power is allowed.
