PXI, multi-cell battery simulator modules target automotive and aerospace applications
Pickering Interfaces launched a new family of battery simulator modules, ideal for Electric Vehicle (EV) battery stack emulation in Battery Management Systems (BMS) test applications. The 41-752A (PXI) and 43-752A (PXIe) modules enable direct voltage and current readback either programmatically or using Pickering’s soft panel control. Each cell simulator is highly accurate, specified at ±5 mV from 1 […]
Bay interface card increases maxim GPS-series power system capacity to more than 20,000 A
To help meet the need for more power from smaller-capacity rectifiers, ABB Power Conversion has developed a new bay interface card, BIC-11. With the upgraded bay interface card, maximum GPS-series power system capacity can be increased from 11,000 amps (A) to more than 20,000A. The bay interface card enables a single system controller to interface […]
Thin-film resistor comes in compact package
Stackpole Electronics’ CSRT2512-UP was developed to provide accurate, high-power current sensing for consumer and industrial electronic devices that exceed the capabilities of most 2512 case sizes available in the industry. The AEC-Q200 compliant CSRT2512-UP has unique thin-film material properties and processing to provide higher continuous power ratings and higher pulse power ratings than other thin […]
LED signaling devices increase levels of ambient light
