PCB Connectors Omnimate Power IT
The compatible power level to fit
each power variant in a device series
Weidmüller offers optimized PCB connectors for devices that are using an IT-type mains power supply. This includes three product lines: SL/BL 7.62 IT MF, SV/BVZ 7.62 IT MF and SU/BUZ 10.16 IT MF; scalable from 24.5 A/2.5 mm2 to 41 A/ 6 mm2 and all the way up to 76 A/16 mm2. This range is suited for devices in the 16-kVA, 28-kVA and 52 kVA power classes. The connectors fulfil the expanded requirements for 5.5 mm of finger safety with IT systems (400 V phase-to-ground voltage in case of error), according to IEC 61800-5-1. Even the SU 10.16 IT male PCB pin header in 10.16-mm pitch features sufficient finger safety with its insulated contact tips. The single flange saves space and serves as a one-hand, safety interlock mechanism. This ensures that the male and female headers snap together safely and automatically. The creepage and clearance distances on the PCB connector have been enhanced, so that there is no limitation for UL approval with 600-V applications – even under difficult design requirements.
The female headers are available with clamping yoke (screw) connections. Even the BVF 7.62 HP PCB connector with PUSH IN spring connection technology fulfils the requirements for IT-system use. The Weidmüller PCB connectors with screw connection technology are always delivered with "wire-ready" clamping points. That means the user must not unscrew the yoke before inserting the wire – this saves time and thus saves money. The PCB connectors for IT mains systems are presently available only from Weidmüller.
