GOODWILL INSTEK PPH-1503

Description

The PPH-1503/1503D are 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 (PPH-1503 : 0.15ms) and a fall time of 0.3ms (PPH-1503 : 0.65ms), which are 100 times faster than that of conventional power supplies. Therefore, the PPH1503/1503D 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 the PPH-1503D, with the sample rate of 64K (PPH-1503: 60K), can conduct pulse current measurement without using a current probe and oscilloscope. The current read back accuracy is 0.2% + 1 A (equals to 11 A) at 5mA range, and the read back resolution is 0.1 A 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 s to dozens of ms when in use. PPH-1503D, different from general power supplies, has the characteristics of fast transient recovery time. While simulating battery to output pulse current, PPH-1503D can quickly compensate the voltage drop caused by pulse current. PPH-1503D'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. Fast transient recovery time and built-in battery simulation function together facilitate PPH-1503D to accurately simulate battery's real behavior pattern so as to conduct product tests.

PPH-1503D is not only suitable for simulating battery, charger and supplying power to DUT, but also ideal for simulating an electronic load to conduct discharge tests with its sink current capability. The sink current function allows the PPH1503/1503D to simulate a voltage source with the sink current capability. Long integration current measurement can be utilized to conduct average current measurement for periodical pulse current in a long period of time that is applied to analyze power consumption for a period of time. One of the applications is to measure the average power consumption of a cellular phone in use so as to conduct the internal RF module parameter analysis. The built-in sequence function of PPH-1503D's CH1 provides users with 1000 steps to edit sequential outputs, including voltage, current and execution time. The built-in DVM function of CH2 has a voltage range from 0 to +20VDC that saves users the cost of purchasing an additional voltage meter.

PPH-1503/1503D are ideal power sources for production line, R&D laboratory, device inspection, maintenance center or applications with the requirements of a fast and accurate power supply with DVM. PPH-1503/1503D support test requirements of Profile1, Profile2 and Profile3 from USB Power Delivery(PD) constructed by USB-IF association.
