RS Pro PEL-3031E Programmable Single Output DC Electronic Load RS Pro PEL-3031E is a programmable single-channel electronic load providing 300 W (1 V ∼ 150 V / 60 A) current sink capabilities. It has seven operating modes, selected on the basis of product test requirements. Different test conditions are met by the Static function (to sink a constant current), the Dynamic function (to periodically switch between two sink conditions) and the Sequence function (to provide tests for more than two sink conditions). The Sequence function can be divided into Normal Sequence and Fast Sequence. Setting parameters for multiple steps can simulate consecutive current changes of real load conditions. A special feature of the RS Pro PEL-3031E is its Soft Start function which enables determination of the rise time of current sink, to decide the required time to reach a set current, resistance or power value. Test adaptability is enhanced by the Timer function (Count Time and Cut Off Time). Features and Benefits CC, CV, CR, CP, CC+CV, CR+CV, CP+CV operating modes Static function/ Dynamic mode (periodically switch between two sink conditions) Programmable Normal Sequence/ Fast Sequence function (fastest 25 μs/step) Soft Start function allows operator to determine the rise time of current sink UVP function for battery discharge tests Timer function for Cut Off Time & Count Time Analog control terminals enable control from external voltage, external resistance and switch Supports peripheral devices and trigger function (TRIG OUT/TRIG IN) Remote Sense function compensates voltage drop from resistance of test leads OCP, OVP, OPP, OTP, RVP, UVP Areas of Application Electronic components Batteries Chargers/portable chargers Adapters Power supply equipment Power products Supplied with User manual CD-ROM, programming manual, quick start guide, power cord, front te...

LD400P, Aim-TTi

LD400P, Aim-TTi

Aim-TTi LD400 Compact DC Electronic Load The Aim-TTi LD400 is an inexpensive, versatile electronic load designed for evaluating and characterising a wide variety of DC power sources including batteries and solar cells as well as electronic power supply units. It has the voltage/current range, multiple operating modes and built-in transient generator to provide test solutions from the design laboratory through to the component test area. The LD400P version adds full bus remote control via USB, RS232, GPIB and LXI compliant LAN (Ethernet) interfaces. The LD400 can operate at voltages below 500mV for currents up to 10A. At higher currents the minimum remains below 1V up to 40A and below 2V up to 80A. This low operating voltage allows the LD400 to be used in many low voltage applications for which other electronic loads may be unsuitable. The LD400 can operate at power levels up to 600W for periods of up to 1 minute. Short term loading is sufficient for many testing applications so this capability significantly increases usefulness. Maximum voltage and current are 80V and 80A with a maximum continuous power capability of 400W (plus the short term capability of 600W). An adjustable drop-out voltage can be set for testing batteries.
