DEMAND BASED COOLING AND MONITORING – FROM A FAN-AND-FILTER UNIT!
MODULAR POWER DISTRIBUTION BUSBAR SYSTEM LAUNCHED
Rittal has launched a new modular Ri4Power busbar system with a 185mm busbar centre distance. The Ri4Power 185mm busbar system is ideal for configuring compact, secure power distribution within Ri4Power switchgear systems or the TS 8 enclosure range. Offering current ratings of up to 1600A and a short time
Rittal has launched a new EC Speed Control, compatible with larger models from the TopTherm EC fan-and-filter unit range (uninstalled air throughputs between 180m3
/h and 900m3 /h). Fan-and-filter units with electronically commutated (EC) motors for electrical
enclosure cooling are already recognised for their lower energy consumption and extended service life. Furthermore, infinite speed control as well as a monitoring signal are much simpler to incorporate in an EC motor than on the AC motor equivalent. The EC Speed Control supports these benefits, and adds a number of others. It can be used to reduce noise output of EC fan-and-filter units, as well as lower energy consumption still further through the ability to control the speed of up to four units. Cooling demand – and hence the required fan speed – is determined by comparing the sensed temperature inside the enclosure with the set-point temperature on the device, from +5˚C to +55˚C. In addition, it is able to closely monitor the status of the fan. The unit provides a
local visual display of the operating status and incorporates an alarm relay for the remote monitoring of over-temperature, fan defect, cable break and sensor failure. This innovative new product sees the humble fan-and-filter unit come of age,
providing demand-based cooling, greater temperature stability inside the enclosure, and performance monitoring, alerting users to any problems with their cooling system. It transforms the fan-and-filter unit into a smart solution perfectly suited to the modern technical era.

withstand rating of 50kA for one second, the Ri4Power system meets the current switchgear standard IEC 61439-1. It is easy to install with no drilling required and integral contact hazard protection, making the system both safe and secure and a quick fix to a punched rail system. The busbar has adaptors ranging from 800A to 1600A for the safe use of standard compact air circuit-breakers available from leading moulded case circuit breaker manufacturers. The circuit breaker can therefore be fitted directly onto the busbar which in turn reduces the amount of space needed within enclosures to accommodate Ri4Power systems. NH slimline fuse-switch disconnectors are available in
single pole or 3-pole versions enabling a very compact busbar distribution system. The new design maximises heat flow for optimum heat dissipation within the enclosure.
