Micropack 24/240 WOR24VDC & 30VDC Rectifier Module

GREAT SMALL POWER

Convection cooled rectifier for system installation in harsh and noise sensitive environments. The module operates with DC as well as AC input, making it even more flexible.

Product Description With an output voltage range of 21.5-36VDC, the Micropack 24/240 WOR covers both traditional 24 and 30VDC systems as well as 24V system with NiCad batteries which requires high boost charging voltage. Wide ranges of both input voltage and operating temperature give the system superior availability. High current ability for selective fuse tripping, keeps the other load running when there is a short circuit in a load branch. Micropack rectifiers arealso designed to have the highest possible immunity level and fulfill the IEC61000-6-5 (immunity, power station and substation) which is unique in the Industry. The Micropack 24V/240W is a power supply for small power systems. Suitable for load ranges typically between 240W and 960W. Perfect for control cabinets, safety systems and building automation applications. Whether you are in need of a simple standalone power supply or a complete power system with battery backup, distribution, remote control and monitoring, the Micropack family is the perfect choice. Its modularity with DIN rail mountable building blocks allows for high flexibility, on site configuration and assembly. Micropack rectifiers are CE marked and UL recognized. Accompanied by a small DIN railed mounted filter the rectifiers can also be used in marine and offshore applications.

Selective load fuse tripping – to avoid all loads going down when one branch is short circuited

SBF The Micropack 24/240 WOR has a selective quick tripping feature; it is able to deliver 55A for 35ms to help tripping the fuse of the short circuited load before the short circuit pulls down the DC supply voltage for the other loads. The number of rectifiers, type and size of the load breaker which needs to be tripped sets the maximum length of the load cables. This is specified in the table below.
