T3PS43203P is a four channel programmable DC power supply. This series not only provides high program resolution (1mV / 0.1mA) and read back resolution (0.1mV / 0.1mA), but also features optimal low-ripple noise characteristics≤ 350µVrms / ≤ 2mArms and output transient recovery capability ≤ 50µS. Independent output on-off switch is provided for each channel. For series and parallel applications of CH1 and CH2, the tracking function of the T3X3200P Series utilizes the internal circuit to automatically switch the output to serial or parallel output without additional external wiring, providing users with convenience not only in operating procedures but also a more stable output. The tracking function design of other brands requires additional external wiring connections for the output in series or parallel. However, excessively long, thin or inconsistent external wiring may cause inaccurate voltage or current output.
