PPH-1503 is a high-speed and high-precision DC Power Supply with dual range of l SV/3A or 9V/5A. PPH-1503 is exclusively designed to meet low power consumption requirements and users’ great demands of accuracy, speed and resolution ofboth voltage and current. Circuits are designed with swift response capability to provide a stable voltage output while experiencing load changes. For example, when switching cellular phone from standby to talk mode, the current consumption will be dramatically changed within milliseconds.
PPH-1503 is designed to simulate battery response when a significant voltage drop occurs. Recovery time of 40 us or less is guaranteed when the maximum voltage drop is within 1OOmV. Moreover, when users change the voltage level and conventional power supply does not have sufficient speed to reach the set level, PPH -1503 provides rise time ofO.l Sms and fall time of0.65ms, which are hundreds times faster than that of the conventional power supplies.
To analyze the transient power consumption of a DUT, the peak of short pulse current and average current measurements over a long period of time are crucial. PPH-1503 provides pulse current and long integration functions, the former can measure the peak value of a pulse, the latter can measure the average value of pulses. PPH-1503 provides DUT with pulse current measurement and analyzes the transient power consumption to qualify the device for specified power consumption requirements. Chargers are often attached to portable battery operated devices. PPH-1503 can sink current, acting as an electronic load, and simulate discharged function of rechargeable batteries. The maximum current is up to 2A. Users can test either battery charged or discharged without changing test equipment.
PPH-1503 provides Limit relay and Trip relay modes and is equipped with corresponding output ports, in which output signais contrai external relay. Under Li mit relay mode and the current li mit is reached, PPH-1503 will switch from Constant Voltage to Constant Current automatically and external relay contrai signal will go high. Under “Trip relay” mode and the current li mit is reached, PPH-1503 will turn output off and relay contrai signal will go high. Furthermore, External Relay contrai can be used if users simultaneously use other devices for test system.
Built-in DVM (Digital Volt-Meter) is designed to measure any point on DUT while PPH-1503 is outputting voltage and current so as to achieve the functionalities of simultaneous output and monitor. Either front or rear panel provides power supply output and DVM input ports for users’ connection consideration.
Users can remotely contrai PPH-1503 via a PC by using USB, GPIB and LAN interfaces which are standardly equipped. PC software can be downloaded from GW lnstek website. These unique features make PPH-1503 an ideal power source for production lines, R&D laboratories, device inspection, maintenance centers or facilities with the requirements of a swift and precise power supply with DVM.
