Programmable power supplies

The WL9 series of low profile switching power supplies now includes higher voltage models with outputs to 135 Vdc. The new supplies are available with an output power rating of 720 watts. In addition to models with ‘slot’ output voltage ranges +/-1 Vdc from the nominal, others have wide adjustment ranges from 0-5 to 0-135 Vdc. All models can be used to provide either a constant voltage or a constant current. Models with wide output voltage ranges can be adjusted down to 0 volts, and both voltage and current can be programmed with 0-10V control voltage inputs. Voltage and current monitor outputs and an inhibit terminal are included on the pluggable connectors that enable easy wiring of the control and input leads. Provisions for N+1 redundancy and paralleling for higher current are optional. Other features include universal input, PFC, “soft start” operation, “Vout ok” indicator and “no load” operation. They are 1.7’ high, and so can be mounted on a rack panel as small as 1U. These power supplies are ideal for applications in process control, ate systems, design and development, motor control, LED light engines, industrial controls, telecommunications, laboratory testing and more.
