智能建筑与家居应用指南
了解Littelfuse技术,帮助您增强楼宇和家居自动化应用的电路保护、电源控制和传感精度。
Reliable fan and compressor motor starters help ensure HVAC system efficiency and consistent indoor climate control. Electronic components made by Littelfuse can boost starter performance. Our solutions include motor start capacitors, mechanical relays, contactors, and overload relays. We also supply current transformers to provide ground fault protection and earth fault relays for extra safety.
HVAC fans and compressors use variable frequency drive (VFD) motors. Ensuring the ac motors speed up and slow down predictably, safely, and efficiently prolongs equipment life. Littelfuse offers many electronic components to achieve that goal, including power bridges for current switching, transformers for ground fault protection, and motor protection relays technicians can monitor via smartphone.
A rooftop unit manufacturer was able to significantly reduce wasted energy by using customdesigned temperature sensors on the refrigerant pipes to control the defrost cycle of a heat pump. The sensors provided fast thermal response and helped reduce energy consumption.
延时中断计时器可监视系统运行时间,并确定延时中断时间应延迟多长时间。系统运行时间越长,计时时间越长,风扇运行时间越长。该定制解决方案专为HVAC客户开发,通过尽量从管道中抽取经过调节的空气来最大程度地提高供暖和制冷效果,从而使系统更加高效并降低能源成本。
Multiple large OEM companies requested a customized three-phase voltage monitor without a manual reset option from the manufacturer to protect what's inside their refrigeration racks. This forced a time-delayed restart by eliminating the possibility of the rack accidentally waiting on a manual reset.
A rooftop unit manufacturer was able to significantly reduce installation time by attaching the leads to the fuse holder. By utilizing pre-assembled 571 (standard) and 572 (snap-mount) panel-mount fuse holders, Littelfuse included a KLK 5 A 600 V ac fuse, 150 °C #12 to #18 wire and 150 °C heat-shrink tubing to help streamline assembly.
A major OEM approached Littelfuse indicating that they were having challenges with their installation tightening processes. Littelfuse designed a hex-screw head that would be better suited for their automated assembly, simplifying the tightening process and reducing assembly errors.
