Designed for EV, aerospace, and power take a look at methods, the compact boards mix security interlocks, calibration help, and four-channel density to validate inverters, BMS, and different next-gen energy electronics.
Pickering Interfaces has launched a brand new household of 1.2 kV PXI and PXIe programmable resistor modules designed to satisfy the rising demand for high-voltage simulation in electrical automobiles, aerospace, and power methods. The 40-230 (PXI) and 42-230 (PXIe) boards present compact, single-slot options that mix four-channel density, huge resistance ranges, and strong security options. The important thing options are:
- Single-slot PXI design saves chassis area
- Gives four-channel high-voltage resistance simulation
- Software program permits exact resistor worth calls with suggestions
- Ensures traceability throughout automated take a look at sequences
- Helps validation of 1 kV+ architectures
- Speeds secure testing for EV, aerospace, and industrial energy methods
With EV platforms shifting to 800 V+ battery architectures and aerospace designs shifting to more-electric methods, the necessity for superior high-voltage validation instruments has change into pressing. Pickering’s new modules permit engineers to securely simulate resistive hundreds, replicate sensor conduct, and insert fault situations when testing inverters, battery administration methods (BMS), and different high-voltage units.
Versatile Excessive-Voltage Simulation
Every channel can mimic the resistance of RTDs, thermistors, or different sensors, enabling hardware-in-the-loop testing with out bodily sensor {hardware}. The boards additionally help fault insertion—open or brief states that confirm whether or not a tool below take a look at responds accurately to situations required by security requirements resembling ISO 6469 (EV security) and IEC 60664 (insulation coordination). The modules additional allow voltage isolation testing, making certain that insulation limitations in BMS and inverter methods meet stringent regulatory necessities—important for automotive and aerospace security compliance.
Recognizing the hazards of 1.2 kV environments, Pickering inbuilt a {hardware} interlock system that forces all relays to their default unpowered state throughout faults. This interlock might be daisy-chained throughout a number of modules for coordinated shutdowns, offering a {hardware} security layer impartial of host PC standing. To streamline calibration, engineers can use an elective cable meeting that bypasses the DUT, permitting direct verification of resistor values with a DMM. This reduces downtime and maintains long-term accuracy in automated take a look at methods.
