Multi-range power supply model 9103 can replace several power supplies on your bench by offering extended operating areas. Unlike conventional supplies with fixed output ratings, this power suppl automatically recalculate voltage and current limits for each setting, providing 320 W output power in any voltage/ current setting within the supply’s rated voltage and current limits.

This family of switching mode power supplies feature a small form factor, auto cross-over for constant voltage (CV) and constant current (CC) operation, 3 voltage/current presets for frequently- used settings and transient operation, and versatile remote control modes. The dual action push button allows the user to set both coarse and fine voltage and current levels quickly and precisely. A remote sensing terminal compensates for voltage drop across load leads.

These features make the 9103 and 9104 suitable for a wide range of applications requiring high current including production testing, telecommunications, R&D, service, and university labs.

Traditional power supplies with rectangular output characteristics are only able to deliver maximum output power at one voltage/current point. The 9103 and 9104 provide greater flexibility over traditional power supplies by extending the operating areas. For example, the 9103 can operate at 42V / 7.6 A, 16 V / 20 A, or any other point on the maximum power curve.

Fully Protected

Have peace of mind knowing that these power supplies come with built-in OVP (overvoltage protection), OTP (overtemperature protection), and OCP (overcurrent protection) circuitry. These protections help prevent serious damage to equipment in case of power supply failure.

Analog Remote Control Capability

Use the included 8-pin connector to wire up to an external variable DC voltage source or variable resistor to remotely control the power supply’s output voltage and current or to turn the output on/off.

Use the front panel preset buttons to quickly set and recall up to 3 different voltage and current settings, to program the power supply for transient mode operation and to output bi-level square, triangular or trapezoidal waveforms.

Control your instrument through remote control PC software or use programming commands to communicate with your instrument.
