The PEL-3000 Series, a single-channel, programmable D.C. electronic load with 0.01 mA current resolution and 16A/ z s current Slew Rate, is very ideal for testing server power supply and SPS (Switching Power Supply) for commercial and industrial computers. For a heavy-duty device like cloud ecosystem running 24-hour nonstop operations, a stable and high-power power supply, ranging from 350W to 1500W, is required to maintain the normal operation of server, Hub, and the equipment of data storage and internet communications. Owing to the increasing demand of data transmission and large scale data storage of telecommunications systems, the infrastructure of internet communications is in the pace of rapid expansion. This has greatly boosted the market demand of telecommunications equipment powered by power supply of 2000W and above. The flexible power combination of PEL-3000 meets the test requirements of present high- power power supply. With respect to battery testing applications such as rechargeable battery for electrical tools, battery module and automobile battery, PEL-3000 has three stand-alone models to offer including 175W, 350W, 1050W and 1050W. By connecting Booster 2100W units with master units, the maximum load capacity of the whole system can reach 9,450W Hence, the PEL-3000 Series fulfills various power testing requirements including medium to low power or high-power power supply.

The PEL-3000 Series has seven operating modes and three operating functions. Among the seven operating modes, four of them are basic operating modes, including constant current, constant voltage, constant resistance, and constant power, and the other three are advanced operating modes including constant current + constant voltage, constant resistance + constant voltage, and constant power + constant voltage. Users must first select operating mode and then operating function based upon the test requirements. Static, Dynamic and Sequence operating functions can be applied to different testing conditions including a fixed load level, switching between two levels or switching among more than two levels. Sequence function is divided into Fast Sequence and Normal Sequence according to the test time of each step. Both Dynamic and Sequence are to assist users to simulate the genuine load change. For instance, PEL-3000 can simulate HEV current consumption to make sure that automobile battery can supply HEV with sufficient power need on the road. By so doing, manufacturers can elevate product quality and reliability.

The adjustable high speed Slew Rate of 16A/ ji s simulates rise and fall speed of different load current so as to test the adequacy of the Response time of power supply. The Soft Start function of the PEL-3000 Series can set current rise time for the moment PEL-3000 is turned on to reduce the abnormal situation of the voltage drop of power supply under test. The adjustable Under Voltage Protection (UVP), GO/NO GO voltage input monitoring function, current monitoring function and Timer Function to control load activation time can be jointly applied to the characteristic tests of battery bleeding to avoid battery damage during bleeding operation. Based upon the functionalities described above, the PEL-3000 Series can test a vast variety of power supply ranging from the fundamental static sink current to complex dynamic load simulations so as to enhance product quality and reliability.

Meets the requirements of high-power supplies
Instek PEL-3000 Series are single-channel, programmable DC electronic loads with 0.01mA current resolution and 16A/?s current slew rate. Static mode provides a fixed load. With Dynamic mode, two test conditions can be switched automatically with adjustable Level, Timing, and Slew Rate. Sequence mode provides a combination of up to 1,000 steps for semi-automated testing.

Flexible power combinations, high-speed, and versatile load simulations
Instek PEL-3000 Series has three stand-alone models with up to 1,050 Watts of load capability. Up to 5 identical units can be wired in parallel to increase the power capability. Additionally, up to four PEL-3211 Watt Booster Units can be wired in parallel with the PEL-3111 to achieve 9,450 Watts of total load capacity.
