Exceptional Output Accuracy and Stability

The DC-3002-II delivers clean, reliable power with notable specifications:

Line Regulation

• Constant Voltage (CV): ≤ 0.01% + 3 mV

• Constant Current (CC): ≤ 0.2% + 3 mA
  These exceptionally tight tolerances mean voltage and current remain steady even as mains input fluctuates.

Load Regulation

• CV: ≤ 0.01% + 3 mV

• CC: ≤ 0.2% + 3 mA
  Regardless of connected load changes, output remains stable—vital for repeatable testing environments.

Ripple & Noise

• Voltage Ripple: ≤ 1 mV RMS (CV mode)

• Current Noise: ≤ 3 mA RMS (CV mode)
  Ultra-low noise levels ensure sensitive analog electronics perform reliably without interference.

Tracking Error

• ≤ 0.5% + 10 mV
  Voltage and current follow their set points closely, delivering predictable power behavior.
  

Indication Accuracy

• ≤ 0.5% + 1 digit
  The LED display gives confidence in readings—especially important during precision tasks.

Intelligent Safety Features

The supply incorporates essential safeguards:

• Constant Current (CC) Mode

• Short-Circuit Protection
  These protect both the power supply and connected devices against overload or accidental short conditions.

Technical Specifications and Dimensions

• Output Voltage: 0–30 V DC

• Output Current: 0–2 A continuous

• Fixed Output: 5 V at 2 A (dedicated terminal)

• Input Power: 220 VAC ±10%, 50 Hz ±2 Hz

• Physical Size: 240 mm (H) × 150 mm (W) × 270 mm (D) — compact and easy to fit into small workspaces

• Standard Accessories: Power cord, user manual, and test lead included for complete usability right out of the box

Dual-Output Versatility & User Convenience

This model provides dual outputs:

• One fully adjustable from 0 to 30 V and 0 to 2 A

• A fixed 5 V, 2 A output ideal for powering logic circuits or USB-based devices

The dual-output design improves usability—engineers can power different circuit elements simultaneously without added adapters.
