The 9185B programmable DC power supply delivers clean, stable, and precise output power due to the supplies’ exceptionally low ripple and noise, low-temperature coefficient, excellent regulation, and fast transient response time characteristics.

This power supply offers SCPI IEEE488.2 compliant USB (standard), RS232, RS485, GPIB, and LAN interfaces, combined with front and rear panel output and remote sense terminals to facilitate test system development and integration. The LAN interface includes a built-in web server that allows users to configure, control, or monitor basic power supply settings.

In addition to a full numerical keypad for convenient data entry, this supply also provides unique features not typically found in comparable power sources, such as LED test modes, modular interface card slots, automatic range selection, and an optional 8-bit bidirectional digital I/O interface.

Versatile connectivity

These power supplies offer SCPI IEEE488.2 compatible standard USB, optional GPIB and LAN interfaces, and an optional 8-bit digital I/O and analog control card to facilitate test system development and integration.

Test sequence execution in list mode

The list mode feature allows users to download a list of commands to the power supply’s internal memory and execute them. A total of 150 steps can be allocated to one of 10 internal memory locations. The test sequence can be programmed from the front panel, remotely through the included application software, or via the USB, GPIB, or LAN interfaces using SCPI commands. Each step’s voltage, current, and duration parameters can be set, with sequences configured for single or repeated execution.

External analog programming interface

The power supplies’ output voltage and current can be controlled by either external analog voltage or resistance. Use a 0-5 V or 0-10 V external DC voltage source, or 0-5 kΩ variable resistor to control the output from zero to full scale.

Application software

Create test sequences for execution in list mode via the GPIB or USB interface using the included PC software.

• Create, save, and load program lists
• View output characteristic curves and export data to a file
• Pass/Fail test monitors maximum and minimum voltage and current values over a specified period of time
