The Instek PPH-1510D 2-Channel Programmable DC Power Supply, Ch1 (15V/3A or 9V/5A), Rear Terminal (4.5V/10A) Ch2 (12V/3A), Ch1 45W, Ch2 36W offers a high precision measurement capability and achieves a maximum resolution of 1mV/0.1uA and a small pulse current width of 33us that satisfy users' 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. This model 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.
The PPH-1510D 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, it 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, 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. Unlike battery, general power supplies, which do not have the characteristics of fast transient recovery time, can not maintain a stable power supply for cellular phone, wireless device, and wearable device which produce large transient pulse current load for hundreds of µs to dozens of ms when in use. The PPH-1510D, different from general power supplies, has the characteristics of fast transient recovery time. While simulating battery to output pulse current, this model can quickly compensate the voltage drop caused by pulse current. The PPH-1510D's CH1 has the built-in battery simulation function, which can define output impedance settings so as to accurately simulate battery's impedance characteristics during battery discharge.
