Laboratory DC Power Supply Unit 100W 0–60V 0–5A 10mV/1mA resolution RS-232 Unit UDP6720

The Unit Laboratory DC Power Supply Unit 100W 0–60V 0–5A 10mV/1mA resolution RS-232 Unit UDP6720 is a compact benchtop supply designed for controlled DC power delivery in laboratory and workshop environments. It provides an adjustable output voltage from 0 to 60 V and an adjustable current up to 5 A, with fine resolution of 10 mV for voltage and 1 mA for current. The unit includes an RS-232 serial interface for remote control and data logging, and is suitable for development, testing, and component characterization where precise voltage and current settings are required.

Advantages

The power supply offers precise adjustment with high resolution, enabling fine control during circuit testing and calibration. Its 100 W power capability supports a wide range of low- to mid-power devices and prototypes. The integrated RS-232 interface enables remote control and simple integration with automation or data acquisition systems. Its compact footprint makes it suitable for small benches and crowded test setups.

Suitable for

• Electronic prototyping and breadboard testing
• Component characterization and bench measurements
• Repair, service, and small-scale production testing
• Educational laboratories and training exercises

When it may not be suitable

This unit is intended for low- to mid-power DC applications up to 100 W; it is not suitable for high-power systems that require higher voltage or current than the specified 60 V/5 A limits. It also lacks advanced interfaces such as LAN or USB by default if those are required for your environment; remote control is provided via RS-232.

Key specifications

• Output voltage range: 0–60 V
• Output current range: 0–5 A
• Maximum output power: 100 W
• Voltage adjustment resolution: 10 mV
• Current adjustment resolution: 1 mA
• Remote interface: RS-232 serial
• Form factor: Compact benchtop unit suitable for laboratory and workshop use

How to use

Place the power supply on a stable, ventilated surface and connect the output terminals to the device under test using appropriate cables and polarity. Set the desired voltage and current limits using the front-panel controls or the RS-232 remote commands, adhering to the specified resolution for precise adjustment. When powering a circuit, limit the current to the safe value for the DUT, then increase voltage gradually while monitoring current and device behavior. Use data logging over RS-232 if you need to record voltage and current values during tests.

What to consider before purchase

• Confirm that 0–60 V and 0–5 A are within the required range for your projects.
• Ensure 100 W maximum power is sufficient for your devices under test.
• Verify that RS-232 remote control meets your automation and logging needs; consider additional adapters if USB or LAN are required.
• Check available bench space and ventilation for thermal management.

Usage recommendations

For safe and repeatable results, always set the current limit below the maximum allowed by the device under test before applying voltage, and monitor the supply output during initial ramp-up. Use shielded leads for sensitive circuits and allow adequate cooling clearance around the unit during prolonged operation.
