GW Instek introduces new PPH-1503D programmable high precision dual-channel DC power supply. PPH-1503D’s CH1 provides dual operational ranges for voltage and current and its total power output is 45W. The dual operational ranges are 0 to 15V/0 to 3A or 0 to 9V/0 to 5A. CH2 provides 0 to 12V/0 to 1.5A with 18W power output.
PPH-1503D’s high precision measurement capability achieves the maximum resolution of 1mV/0.1uA and the smallest pulse current width of 33us that satisfy customers’ measurement application requirements of high resolution and pulse current. Fast load current variation will result in voltage sag for general power supplies that will have an impact on DUT’s internal circuit operation. PPH-1503D is equipped with the excellent transient recovery time, which can, in less than 40us, recover the output voltage to within 100mV of the previous voltage output when the current level changes from 10% to 100% of the full scale. Furthermore, conventional power supplies do not have sufficient response speed to promptly respond to set voltage value once the set voltage is changed. PPH-1503D has a rise time of 0.2ms and a fall time of 0.3ms, which are 100 times faster than that of conventional power supplies. Therefore, PPH-1503D can provide DUT with a stable output voltage even when DUT is operating under large transient current output. The internal high-speed sampling circuit design of PPH-1503D, with the sample rate of 64K, can conduct pulse current measurement without using a current probe and oscilloscope. The current read back accuracy is 0.2%+1uA (equals to 11uA) at 5mA range, and the read back resolution is 0.1uA that allow DUT to be measured with a high accuracy level.
