Warnings Hazardous Voltages The INPUT AND OUTPUT POWER connectors and cables of the SynQor MPC may have voltages that are unsafe. INJURY OR DEATH ON CONTACT may result. Appropriate safety precautions should be taken. All connections should be made in accordance with LOCAL ELECTRICAL CODES.
MPC while the MPC is operating. No User Serviceable Parts The SynQor MPC has no user serviceable parts inside of it. DO NOT REMOVE the cover of the MPC or any of its connectors. Only factory trained personnel should perform repairs.
Front panel LEDs and an audible alarm provide information on the status of the MPC. The MPC-1500 Series products can draw power from an AC input having a wide range of voltage and frequency levels, or from an optional 28 V nominal DC input. The AC input has priority over the DC input.
General Product Information Product Topology The SynQor MPC-1500 Series products use a true on-line double conversion topology that provides protection 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 profiles so that the input power sources are not subjected to these disturbances.

Total Output Power that can be derived from the AC INPUT The total MPC output power (the AC OUTPUT power plus the optional DC OUTPUT power) for the MPC-1500 series is rated at 1250 W for an ambient temperature as high as 55 C (131 F).
Page 15
AC INPUT would be 1125 W at an AC INPUT voltage of 90 Vrms and an ambient temperature of 50 C (122 F). A higher output power than this would cause the MPC to switch over to its DC INPUT. 006-0006452 MPC-1500 Operator Guide Rev P 15 of 48 03/03/2021 www.synqor.com...

While this is an issue for all of the power cables, it is particularly important for the DC INPUT and DC2 Output cables because the current flowing through it is very high (as high as 65 A for the MPC-1500 Series) and the voltage across it is already relatively small (as low as 22 V). In fact, a common problem that arises (when the DC INPUT cable has too small a wire) is that the voltage seen at the DC INPUT of the MPC falls below the minimum specified value of 22 V even though the voltage at the source of the DC power is greater than 22 V.
• The MPC will disable its outputs and shut down. • It is not necessary to move the AC BREAKER on the rear panel of the MPC to the OFF position. 006-0006452 MPC-1500 Operator Guide Rev P 19 of 48 03/03/2021 www.synqor.com...
MPC. However, the SynQor MPC is capable of having any of its input or output power cables connected at any time (if safely done), including when the MPC is turned on and delivering power to the load.
Operation Cooling System The SynQor MPC-1500 Series products are cooled by fans that draw air into the intake below the front panel and exhaust it out the two fan ports on the rear panel. Care should be taken to ensure there is no obstruction to this airflow, either at the front intake or the rear exhaust ports.

Operation Operating Environment The SynQor MPC-1500 Series is designed for the extreme environmental conditions of military and aerospace applications. All the electronic circuitry is contained in a sealed, weather-proof, shock-proof chamber constructed of die-cast aluminum. Only the redundant, water-proof cooling fans are exposed to the environment.

See the following pages for details. These cables are unique to the –R paralleling option, and cannot be used with –F paralleling option units. Contact the SynQor factory for Single Phase systems larger than 3 MPC units, or for Split Phase and 3-Phase systems.
Parallel Configurations of the AC OUTPUTS: Up to Three Units Multi-unit Configurations The chart below shows four possible ways the AC OUTPUTS of up to three SynQor MPC units can be connected together. Each configuration will be discussed in more detail in the following pages.
Parallel Connection of the AC OUTPUTS Two or three SynQor MPC units can have their AC OUTPUTS connected in parallel to deliver two or three time the output power and output current of a single unit. Units can also be connected to form 1+1 or 2+1 redundant systems.

Several problems could arise with such a load: ▪ The MPC fails to start the load: The SynQor MPC is designed to try various start-up routines when it is first turned on to overcome the problem of surge currents with some loads. There are five such routines (or repetitions of a given routine) that are tried.

MPC will determine that the DC INPUT is out of range and will shut down. ▪ Since the MPC no longer draws current from the DC INPUT, the voltage drop across the DC INPUT cable goes back to zero volts. 006-0006452 MPC-1500 Operator Guide Rev P 46 of 48 03/03/2021 www.synqor.com...
