These 14 outlet Sequential Startup Mains Distribution Units replace the SMU 112B/D, SMR 110B/D and SMS 112P versions. A custom micro-controller switches the outlets on sequentially with a fixed delay of 600ms between outlets as standard.
Each outlet is individually fused and has a bi-colour LED indicator to display its status. As the relays switch each outlet on, it's associated LED will turn Green. If for any reason the fuse blows, or the relay fails to switch, then the LED will turn Red to indicate a fault condition.
All IEC outlet connectors are 10 Amp rated, cables being secured to the integral tie-bar. The input connector is a 20 Amp Neutrik powerCON, a mating connector is supplied.
The remote start function of the SMR 110B is available in the SMU 114P MDU by linking two pins on the rear panel mounted D connector.
The SMS 114P has a serial connection on the rear panel allowing remote control and monitoring from third party building management systems, plus comprehensive programming of the internal sequences.
These units are supplied with an illuminated on/off switch.
Please Note: These units are designed for EU mains or similar, 230VAC +/-10% with neutral and earth nominally at the same potential. They are not for use on lower mains voltages, for example 100-120VAC, although custom builds are possible for larger orders. The units should never be used on rare 'balanced' mains where live and neutral are centred on earth, L/N measuring similar voltages to earth. Balanced mains requires fusing in both live and neutral distribution.
