(*) All the units that are connected in the same system need to be on the same power line. For example; any FlowTrac II or LoadTrac II, which is connected to Cyclic – RM control unit, needs to be on the same power line with Cyclic – RM unit.
Power plug selection:
Below are suggested website to check the power plug for your country.
Check with this web site: https://www.worldstandards.eu/electricity/spread-plug-types-map/
Go to Products => Power cords in this web site: http://www.megaelectronics.com/power-cords/#
UPS selection:
The specification of the UPS should be determined as follows:
Output voltage has to match the voltage used by your system (i.e. 110 VAC or 208-240VAC and single or 3 phase output) and the maximum output power has to match the system’s total added power. If a large UPS is not available or practical, you can connect the systems to multiple UPS units.
Example for a system power sizing:
Triaxial system with one LoadTrac II and two FlowTrac II’s: Total power = 340 + 2 * 120 = 580 Watts.
We also recommend the exclusive use of line interactive UPS. Please see below figure for its schematic.
Figure: Schematic of line interactive UPS
In this design, the battery-to-AC power converter (inverter) is always connected to the output of the UPS. Operating the inverter in reverse during times when the input AC power is normal provides battery charging.
When the input power fails, the transfer switch opens and the power flows from the battery to the UPS output. With the inverter always on and connected to the output, this design provides additional filtering and yields reduced switching transients when compared with the Standby UPS topology.
In addition, the Line Interactive design usually incorporates a tap-changing transformer. This adds voltage regulation by adjusting transformer taps as the input voltage varies. Voltage regulation is an important feature when low voltage conditions exist, otherwise the UPS would transfer to battery and then eventually down the load. This topology is inherently very efficient which leads to high reliability while at the same time providing superior power protection.
Specific to the 3 phase large cyclic direct simple shear system;
Example of a suitable UPS is given in the link below: Tripp-lite, Model Number: SUT20K
