Compact 800W Benchtop DC Loads
The 41T Bench Series includes two stand-alone and two modular models, offering either high current (up to 160A) or high voltage (up to 500V). All models feature dual range operation for enhanced accuracy and resolution, with 800W continuous power and 1600W in TURBO mode for short-term overloads up to 3× rated current or power. Input ranges include 0–80V (41T08160) and 0–500V (41T5040), each supporting a wide V-I constant power load profile. The compact design suits both bench use and rack mounting, with modular versions compatible with the 44M02 and 44M04 mainframes.
APS 41T Series DC loads provide flexible testing with built-in metering, automated sequencing, and fast slew rates. Features include OCP/OPP and dynamic CC modes for power supplies, battery discharge with Lithium BMS profiles, trip testing for protection devices, and MPPT for solar panels.
- Versatile Loads – Microcontroller-based with built-in V, I, P, R metering.
- Power Supplies – Low-V/high-I or high-V/low-I models; supports sequencing and fast slew rates for loop/stability tests.
- Design Verification – OCP/OPP modes, dynamic CC, and analog input for arbitrary waveforms.
- Batteries – Programmable discharge, high-resolution current, built-in profiles, and Lithium BMS test mode.
- Protection Device Testing – Automated step-current tests for fuses, breakers, and PTCs.
- Solar Testing – MPPT mode for panel and cell testing.
The Quick Charger Tester (Opt QCT) is a single-channel controller for R&D testing and verification of modern fast chargers. It simulates fast charge protocols for mobile phones, tablets, and notebooks, enabling rapid charger evaluation.
Supported Charging Protocols are: QC2.0, QC3.0, PE+, PE+2.0, USB PD2.0
