connector, even if the MPS/MPPS appears to be o.
▪Do not make contact with the terminals of the AC input connector.
▪Always connect the cable to the MPS/MPPS before it is connected to the source of AC power.
▪ Always disconnect the AC input cable from the source of AC power before disconnecng
it from the MPS/MPPS.
▪If the AC input cable is connected to the source of AC power and not connected to the
MPS/MPPS, do not contact the exposed terminals of the AC input cable.
▪Do not assume that the source of AC power is not present.
▪ Connecons between the AC input cable and the source of AC power should not be accessible.
• For the MPPS DC OUTPUT cable and connector:
▪The DC output terminals of the MPPS may be hazardous, depending on the model and user
commanded voltage. Never assume the terminals of the DC output connector or the wires
of the DC output cable are safe to contact, even if the MPPS appears to be o.
▪The DC output terminals of the MPPS are isolated from the AC input with reinforced
safety insulation.
• For the MPS DC OUTPUT cable and connector:
▪The rated DC output voltage of the MPS is below the level considered hazardous.
▪ The DC output terminals of the MPS are isolated from the AC input with reinforced

Product Topology: MPS
The SynQor MPS‑4000 Series products use an isolated topology that provides protecon to
the load from spikes, noise, surges, brownouts, blackouts, etc. in the input power sources.
They also provide smoothing of load transients and nonlinear load proles so that the input
power source is not subjected to these disturbances.
EMI lters are present at all external inputs and outputs

Power ows from the AC INPUT through an AC‑DC converter that has Power Factor Correcon
(PFC) and high‑frequency safety isolaon.
The DC outputs at various voltage and power levels are available. The DC output voltage,
and maximum output current can be programmed by the user. The DC output can deliver
up to 4000W.
Bulk energy storage capacitors are connected to the mid-bus to help smooth imbalances in
power ow between the inputs and outputs of the MPPS.
An ideal diode on the output of the MPPS prevents circulang currents when Units are placed
in parallel. The ideal diode also provides some degree of redundancy should one MPPS in a
paralleled system experience a failure.
