Keithley 2230-30-3 – 195W DC Power Supply

The Keithley 2230-30-3 is a 195 W triple-output programmable DC power supply engineered for multi-channel test and measurement applications. Three independent, electrically isolated output channels deliver flexible power distribution to circuits requiring different reference points or polarities. Linear regulation maintains output noise below 1 mV rms, protecting sensitive devices under test from ripple interference.

## Technical Specifications

**Output Configuration**
• Two channels: 0 to 30 V DC, 0 to 3 A each
• One channel: 0 to 5 V DC, 0 to 3 A
• Voltage resolution: 1 mV
• Current resolution: 1 mA
• Voltage accuracy: 0.03% basic
• Current accuracy: 0.1% basic
• Output ripple and noise: <1 mV rms
• Overvoltage protection (OVP): Enabled on all channels

## Key Features

**Channel Flexibility**
All three channels operate independently with isolated outputs, eliminating cross-channel interaction. Series the two 30 V channels to reach 60 V. Parallel multiple channels to increase current capacity beyond 3 A per-channel limits. Remote sensing on all outputs compensates for voltage drops across test leads, delivering programmed voltage directly to the load.

**Control & Programmability**
Front-panel numerical keypad enables direct value entry. Up to 30 setup memory locations store frequently used configurations. Per-channel output timer provides automated control. Simultaneous display of voltage and current across all three channels. Each channel switches on and off independently without affecting others.

**Interfaces**
USB 2.0 (USBTMC-compatible) and RS-232 standard on all units. GPIB available on "G" model variants. Rear-panel output via 15-pin terminal block socket; RS-232 via DB-9; USB Type A to B connector.

**Software Integration**
LabView and IVI drivers support semi-automated and fully automated test systems. KickStart software available for interactive instrument control and data logging.

## Typical Applications

Multi-rail circuit development, isolated power subsystem testing, automated test sequences with mixed voltage and current requirements, device characterization under variable load conditions.

## Compatibility & Integration

Standard USB and RS-232 interfaces integrate into existing lab environments. Optional GPIB enables integration into legacy GPIB-based automated test systems. Isolated outputs support circuits with floating or multiple ground references without external isolation modules.
