AC Input Connection

Warning

Disconnect AC power from the mains and measure the AC input terminals to ground to ensure 0 Vac is present before attempting any installation procedure.

AC power is wired to the TS Series MagnaDC power supply by attaching three cables plus ground for 3-phase installations or two cables plus ground for 1-phase installations. The TS Series MagnaDC power supply is phase orientation insensitive, allowing the phases to be connected in any order; the ground connection, however, must be connected to ground stud labeled with a ground symbol.

Magna-Power recommends cables per the recommendations of the National Electrical Code or Suggested Ampacities of 4-Conductor Type S or SO Cable, with one end stripped of 0.5 in (12.7 mm) of insulation and securely crimped to a 1/4 in (6.3 mm) ring terminal in accordance with UL486A.

Remove the nut and mating lock washer from the TS Series MagnaDC power supply 1/4”-20 threaded AC input studs. Then place the ring terminal crimped to the AC input wire through the AC input stud, reattach and securely fasten the lock washer and mating nut. The recommended torque for the AC input connection is 4.2 lb-ft (5.7 Nm).

6U and 9U TS Series models have external cables that parallel the modules’ AC input studs to a single module’s AC input studs. Ensure that your external AC input wiring is made only to the AC input studs that have the mating nuts and lock washers. No additional connections are necessary for the module that has metal caps on its AC input studs. In addition, the two modules are grounded together internally; only one ground connection is required, which is on the same module where the external AC input wiring is made.

8U, 12U, and 16U TS Series models have only one exposed AC connection point for each phase. AC cabling should be routed through the provided grommet and connected to the studs behind the AC input cover.

Note

The cable recommendations provided are for reference purposes only. Always consult local electrical code requirements to ensure compliance.

After connections are made, the provided protective covers for the AC input and DC output can optionally be installed and securely fastened to the chassis using three screws per cover. This programmable DC power supply is designed to be permanently connected to the power source requiring a readily accessible disconnect device incorporated into the fixed wiring.

AC Input Current

The AC input current rating is specified on the product’s serial label, typically located on the top cover near the AC input terminals.

The following tables provides the per phase maximum input current rating for the available AC input voltages and power levels of the TS Series. All AC input currents factor in efficiency and power factor. With the product’s AC soft-start circuitry, there is no additional in-rush current; the numbers in the following table provides the peak AC current draw at full load. These same AC input current ratings are also specified on the product’s serial label.

Fuse Rating

MagnaDC power supplies contain a variety of power and control fuses. For TS Series MagnaDC power supply products with a 1-phase input, there are two (2) power fuses and two (2) control fuses. For TS Series products with a 3-phase input, there are three (3) power fuses per module and two (2) control fuses per module. Fuse ratings for TS Series MagnaDC power supply provides the fuses ratings and recommended replacements. Magna-Power recommends using a time-delay fuse.

In the event of a fuse fault, power must be removed from the supply and the fuse must be replaced to correct this condition. A cleared power fuse usually indicates a power stage failure, often requiring factory attention. In addition, a cleared fuse can be caused by power surges from lightning storms or other AC transient events.

Warning

To avoid personal injury or damage to the TS Series MagnaDC power supply, use only the specified replacement fuses.

Note

MT Series Products Only. For the power processing circuitry, MT Series programmable DC power supplies are equipped with a 3-phase AC breaker instead of fuses. In the event the breaker is tripped or if the breaker is not engaged after applying turning on control power via the front panel control power switch, the FSE alarm will indicate. After engaging the breaker to the on position and pressing the Clear button, the FSE alarm will no longer be present.
