OWON Technology

OWON Technology P4305 30V 5A Single Channel Linear DC Power Supply measurement tool

SKU CH-YWZM-ESAGC MPN P4305

Single-channel linear DC supply delivers 0–30 V at 5 A with 1 mV/1 mA resolution and low ripple

  • Precise voltage control with 1 mV setting resolution
  • Clean power delivery featuring ≤ 1 mVrms ripple and noise
  • Remote automation via RS232 interface supporting SCPI and LabVIEW
  • Compact bench footprint at 117 × 295 × 194 mm for easy transport
  • Built-in protection with over-voltage and over-current safeguards

Single-Channel 30 V 5 A Linear Supply

The OWON P4305 is a benchtop linear DC power supply that delivers 0-30 V and 0-5 A from a single channel with a total output of 150 W. It is built for engineers, technicians and students who need clean, stable power for circuit development, repair or classroom experiments.

Suits bench work needing low noise.

The 1 mV/1 mA resolution and ≤4 mVp-p ripple make it a good fit for analogue prototyping, sensor biasing and general lab tasks. Users who require simultaneous dual or triple outputs, remote sensing terminals or higher current ranges should look at other equipment.

Desktop setup with RS-232 control

Place the unit on a bench, connect the supplied mains cable and serial line, then configure via the 3.7-inch colour LCD or SCPI commands over RS-232. The smart fan manages thermals automatically; the only common issue is forgetting to select the correct 5-group memory slot before recalling a stored setup.

Questions about this item

What AC mains supply do I need for the P4305 to operate?

The unit accepts 100–240 V AC, so any standard mains outlet in that range will power it.

Can I control the P4305 from a legacy PC that only has an RS-232 port?

Yes, the built-in RS-232 interface and included serial cable let you send SCPI or LabVIEW commands directly from that PC.

How do I verify the P4305 is regulating correctly after I connect a load?

Watch the 3.7-inch LCD readback; it shows voltage to 1 mV and current to 1 mA, matching the setpoint accuracy of ±0.03 % + 10 mV for voltage and ±0.1 % + 5 mA for current.
