Installation Manual AC Power Source California Instruments Models: MX15-1 MX15-1Pi MX30/2-1Pi MX30/2-1Pi-MB MX45/3-1Pi MX45/3-1Pi-MB Rev C, March 2011.
Important Safety Instructions Before applying power to the system, verify that your product is configured properly for your particular application. Hazardous voltages may be present when covers are removed. Qualified personnel must use extreme caution when servicing this equipment. Circuit boards, test points, and output voltages also may be floating above WARNING (below) chassis ground.

Product Family: MX15 Series Warranty Period: One Year WARRANTY TERMS AMETEK Programmable Power, Inc. (“AMETEK”), provides this written warranty covering the Product stated above, and if the Buyer discovers and notifies AMETEK in writing of any defect in material or workmanship within the applicable warranty period stated above, then AMETEK may, at its option: repair or replace the Product;...
(option -400), 440 V (option -480). Figure 2-1: The MX15 Power Source CAUTION: Do not connect 400, 440, or 480V into a unit set for 208 or 230V unit, the result could be a severely damaged unit. Always check the input rating on the model number tag before connecting AC input power.
AC input connections are to be made directly to the input fuse block. The input fuse block is located on the lower right hand corner of the rear of the MX15 chassis. To access the input fuse connection block, the protective rear cover needs to be removed first.
The front cover must be re- installed prior to use and the strain relief provisions located at the rear bottom of the unit must be used to maintain protection against hazardous conditions. MX15 Series...
LV Power supply of the MX15 chassis only. The LV Power supply provides DC bias power to the entire MX15 system. The AC input power is routed through a set of three AC line fuses (F1-A, F1-B and F1-C) located in the lower right bottom corner of the MX15 (Looking from the rear).
Installation Manual CAUTION: The AC input fuses can only be checked if the MX15 is completely de-energized and disconnected from any AC power input. Note: Under no circumstances should AC input power be applied if one or more of the AC input line fuses have failed and opened up.
If the EUT changes frequently, you may want to consider using some quick disconnect scheme external to the MX15 so it will not be necessary to power down the MX15 and remove the front covers. This can take the form of a panel-mounted socket of sufficient current and voltage rating.
REMOVING THE REAR PANEL. The correct standard size Allen wrench for connecting output wiring to TB1 is supplied with each MX15 in the ship kit. Look for a brown envelope. If the correct tools cannot be found, contact California Instruments customer service at support@calinst.com...
MX15-1 and MX15-1Pi Output Wiring Diagram Figure 2-6 shows the required output connections for a MX15-1 or MX15-1Pi. Always disconnect all input power from the MX15 before removing the rear panel cover that provides access to the input and output terminal connections.
MX30/2 and MX45/3 systems are shipped with external output terminal blocks that enable the output wiring from two or three chassis to be combined, providing a single point of connection to the EUT. These blocks are not enclosed however. Figure 2-7: MX30/2 or MX30/2-MB Output Wiring MX15 Series...
2.6.4 Multi-Chassis Output Connections If two or more MX15 chassis are used to form a single power system, the outputs of all chassis need to be combined (paralleled). This can be done directly at the EUT if convenient or using the provided heavy-duty terminal block.
A set of two identical System Interface connectors, P8 and P9 is located on the rear panel of each MX15 chassis. The system interface is used to connect the multiple MX15 power sources in a Master/Auxiliary configuration to create MX30/2 and MX45/3 models. In these configurations, only the Master MX15 power source has a built-in controller and front panel.

Master units each have their own controller but can be configured as auxiliary units by disconnecting the ribbon cable marked J17 between the controller and the system interface board (P/N 7005-701-1). This disables the controller and allows the MX15 to operate as an Auxiliary unit. (Requires removal of the top cover) When used as a multi-cabinet system for higher power applications, the controllers in the unit(s) acting as the auxiliary to the master are either disabled or not present.
Master/Auxiliary which requires each chassis to have it's own controller. As such, it is possible to create 1, 2, or 3 phase power systems using 2 to 3 MX15 chassis. For most single phase configurations, the normal multi-box mode of operation as described in section 2.8 is recommended as it provides a single controller (and GPIB/RS232 control interface).
California Instruments 2.9.2 Clock/Lock Initialization Settings The mode of operation of the MX15 is determined by the MODE setting in the CONTROL menu. If the clock and lock option is enabled, three choices will be available for this field: STAN, MAST, and AUX.
Make sure the power resistor has sufficient power dissipation capability - up to 15 KW for full load test per MX15 - and that the load used does not exceed the maximum power rating of the MX15.
