Ablerex MPDU-250 Maintenance Bypass PDU

A deliberate path for UPS maintenance The Ablerex MPDU-250 combines a manual maintenance-bypass function with IEC socket distribution. It is intended for a compatible 6–10kVA UPS installation where the power path must be planned for servicing as well as normal operation. A defined bypass arrangement lets a qualified operator transfer supported loads between the UPS output and utility supply using the prescribed procedure. During utility bypass, the connected load depends on that supply rather than the UPS battery and conditioning. Highlights Bypass and distribution Manual maintenance-bypass function 8 × IEC C13 and 4 × IEC C19 output sockets A defined power arrangement For the specified compatible 6–10kVA UPS installation 230V application; up to 50A rating subject to the complete installation Built for rack integration 4U enclosure 440 × 176 × 120mm (W × H × D) Key Features Plan servicing before it is needed The bypass arrangement gives a qualified operator a defined route for moving a supported load away from the UPS during maintenance. The correct operating sequence, source condition and load suitability must be established as part of the installation. Keep normal and bypass operation clear Normal operation routes power through the UPS. Utility bypass places the connected equipment on the available utility source. This does not provide battery backup during bypass, and it should not be described as automatic failover or protection against every interruption. Connect supported equipment through IEC outlets Eight C13 and four C19 outlets support a planned mix of equipment connections. The overall load remains limited by the UPS, bypass unit, supply, cables and protection; the socket count does not multiply the available capacity. Match the terminal connections and protection MPDU-250 uses a terminal-based electrical arrangement for the mains and UPS connections. Select it with the actual UPS model, supply current and installation in view, and have the connection and protection established by a suitably qualified installer. Compatible Models Compatible Ablerex 6–10kVA UPS installations specified for MPDU-250, including supported MARS/MSII arrangements after connection and current-rating verification. Confirm the exact UPS model, wiring and protective arrangement; it is not a universal bypass accessory for every UPS. Summary MPDU-250 brings manual maintenance bypass and IEC distribution into one rack unit for a correctly matched UPS installation. Its value comes from a planned electrical design and a clear servicing procedure, with the limits of utility bypass understood by the operator. Frequently asked questions What does MPDU-250 combine?ExpandCollapse It combines a manual maintenance-bypass function and IEC socket distribution for a specified compatible 6–10kVA UPS arrangement. Does it transfer sources automatically?ExpandCollapse No. Its maintenance-bypass operation is manual. It is not a substitute for a separately specified automatic transfer switch. What sockets are available?ExpandCollapse It provides eight IEC C13 sockets and four IEC C19 sockets, alongside the terminal-based electrical connections shown for the unit. Will the load still have UPS battery protection in bypass?ExpandCollapse During utility bypass, the load depends on the utility supply rather than the UPS battery and conditioning. Plan the bypass procedure and connected equipment accordingly. What rack space does it occupy?ExpandCollapse The enclosure is 4U, with dimensions of 440 × 176 × 120mm (W × H × D). Allow additional space for wiring, cable bend and safe access. Can I install it as a normal plug strip?ExpandCollapse No. This terminal-connected unit needs a correctly designed electrical connection and protection arrangement, implemented by a suitably qualified installer.
