SPD3303X

DC Power Supply

Output Rating

CH1: 0~32 V, 0~3.2 A
CH2: 0~32 V, 0~3.2 A
CH3: 2.5/3.3/5.0 V, 3.2 A

Resolution

SPD3303X-E: 10 mV/10 mA
SPD3303X: 1 mV/1 mA

Accurately supply your needs of stability and versatility!

The SPD3303X /X-E is robust and stable, and can accurately simulate even small voltage or current changes, fully meeting the power requirements of the load.
 

· Ultra-high resolution: 1 mV, 1 mA
· Excellent setting and readback accuracy to ensure accurate and pure output
· Support panel programming and timing output
· 3 independently controlled and isolated outputs

The series-parallel function combines two power supplies into one power supply, which expands the output power range of a single power supply, which brings convenience in some applications. The three independent power supplies can individually control the output switch, and they can be turned on or off at the same time.

Main Features

  • 3 independently controlled and isolated outputs: Two 32 V/3.2 A, one 2.5 V / 3.3 V / 5 V / 3.2 A × 1, total 220 W

  • 5 digit Voltage/4 digit Current Display, Minimum Resolution: 1 mV/1 mA  (SPD3303X)

  • Timing function provides programmed output steps

  • 4.3 inch true color TFT- LCD 480 x 272 display

  • 3 types of output modes: independent, series  (60 V max), and parallel  (6.4 A max)
