1 Application Paper AP000001E contents Description Page XT Starter with XTOB Thermal OL XT Manual Motor Controller Control power transformer selection Power supply selection Control power transformer sizing sheet Power supply sizing sheets introduction Reducing costs is necessary for OEMs to maintain a competitive edge. Eaton s line of IEC motor starters was designed with enhanced features and benefits that help OEMs reduce material costs while improving reliability, installation, usability, and safety. The newest line of Eaton s IEC motor starters includes new innovations in coil design, yielding greater pickup tolerances while reducing energy consumption. In many common scenarios where the control panel contains three contactors or more, switching to the Eaton XT contactor from another contactor line typically allows users to reduce their control power transformer or power supply by at least one size, with greater likelihood of larger reductions as more contactors are added to the control panel. This application note explains how control power are sized. Coil consumption tables for Eaton XT and competitive lines are provided in Tables 7 and Table 8. A CPT/ power supply calculation sheet is provided at the end of this document. Electronic Coil and Magnet Armature

2 Application Paper AP000001E How to size a control power transformer (CPT) CPTs are most commonly identified by their nominal, steady-state VA capacity, but they also have a maximum rating describing the amount of inrush they can support on the secondary. Some loads, such as relay coils or contactor coils, require a temporary spike in power once power is applied. Then after the contacts have been pulled in, very little power is needed to hold the contacts closed. Other devices, such as pilot lights, consume the same amount of energy when power is first applied through to continued operation. CPTs should be selected to ensure enough power is available on the secondary side to handle the inrush power needs of the loads the CPT supplies. Each CPT has a maximum inrush power rating. This inrush VA is the critical rating used to size CPTs. This value is determined using the following formula: where Total Inrush is the total sum of all the inrush power of the loads applied to the CPT, and Sealed Inrush is the total sum of all the sealed power of the loads applied to the CPT. Once the Inrush power requirement on the CPT has been determined, the CPT is sized from the selection chart using either the 85%, 90%, or 95% secondary voltage. This means that the secondary voltage of the CPT will not dip below the respective percentage provided that the inrush power put on the CPT doesn't exceed the inrush power from the selection chart. 90% or 95% is mostly recommended, as exceeding the inrush power rating of the CPT could lead to a deeper decrease in coil voltage on the secondary, which could cause the contactor and relay coils or other devices to prematurely fail. CPT INRUSH VA = (Total Inrush) 2 + (Total Sealed) 2 Example A control panel contains qty (1) 7A contactor, qty (2) 18A contactors, qty (2) relays, and qty (6) indicating lights. These loads are supplied 120 Vac from a CPT with a 80 Vac primary. Determine the CPT size needed. In this example, the CPT needs to be able to provide 250 VA to support the inrush demand of the loads. The C0075E2A has enough inrush VA capacity to support these loads. Table 1.

NNote: See Table for CPT selection charts for a variety of primary and secondary voltages

3 How to size a power supply Power supplies are sized based on the amount of inrush (surge) and sealed (nominal or steady-state) power demands of the loads applied to the power supply. The respective loads are calculated by simply summing the loads, both for inrush and sealed. Application Paper AP000001E The power supply is selected based on these calculated demands on the power supply, and any other load specifications for the respective power supply, such as minimum time allotment between surges (inrush). Always be sure to verify proper application per the power supply specifications. Inrush load = inrush load 1 + inrush load inrush load n Nominal load = sealed load 1 + sealed load sealed load n For extended operational life of the power supply, increase the calculated nominal load by 20%. Example Select a 2 Vdc power supply for a control panel containing qty (8) 7A contactors, qty () 18A contactors, qty (2) relays, and qty (5) indicating lights. In this example, the PSG60E has enough capacity to handle the surge (inrush) and nominal (steady-state) demand of the loads. Current = Power/Voltage Table.
