Safety Considerations
When properly installed in the mainframe, the power module is part of a subsystem that constitutes a Safety Class 1
instrument. The power module has a protective earth connection that is completed through a contact spring in the
mainframe backplane. When the power module is moved in and out of the mainframe, the earth ground connection is
made before ac power is connected and is removed after ac power is disconnected.
Instrument Identification
The power module is identified by a unique two-part serial number, such as 3139A 00177, visible on the module pull tab
when it is in the fully extended position. The first part, or prefix, is a number-letter combination that provides the
following information:
3130 The year and week of manufacture or last significant design change. Add 1960 to the first two digits to
determine the year. For example, 31=1991, 32=1992, etc. The last two digits specify the week of the
year (30 = the 30th week).
A The letter indicates the country of manufacture, where A = USA.

Description
The HP 66lxxA Series Power Modules are used in the HP 66000 Modular Power System (MPS) mainframe to provide a
range of dc output voltages and currents. The modules are installed or removed from the front of the mainframe without
the need for disconnecting any wires. Modules may be connected in series or parallel to provide increased output voltages
or currents. The modules can be equipped with optional isolation and polarity reversal relays that are built into the
module output connector.
The power module front panel has digital readouts of output voltage and current. It also has annunciators that indicate:
• constant voltage, constant current, or unregulated operation
• activation of a protection circuit
• disabling of the output
• remote operation (addressed by the controller)
Programming
The power module is programmed over the HP-IB from a controller using SCPI (Standard Commands for Programmable
Instruments). This makes power module programs compatible with those of all other instruments controlled with this
language. Among the functions that can be programmed are output voltage and current, OVP (overvoltage protection),
OCP (overcurrent protection), status registers, output relays, and output voltage and current calibration.
In addition, the power module has programmable trigger, list, and RI/DFI (remote inhibit/discrete fault indicator)
subsystems. Triggers can occur from signals at the mainframe TRIG IN jack or from selected internal events. The list
subsystem generates preprogrammed sequential outputs in response to triggers. The RI/DFI subsystem generates an
output on the mainframe FLT line in response to selected internal events or turns off the output in response to an input on
the mainframe INH line.
The power module also can be programmed locally from the optional HP 66001A MPS Keyboard. The keyboard has an
alphabetical command menu for all power module SCPI commands. By scrolling through the menu and entering the
appropriate parameters, commands may be created for development or debugging.
Output Characteristic
The power module can operate in either CV (constant voltage) or CC (constant current) mode over its voltage and current
output range (see Table 1-1). The operating locus (see Output Characteristic Curve in Table 1-2) shows a single-range,
limited two-quadrant capability. The operating point is determined by the voltage setting (VS), the current setting (IS) and
the load impedance (Rl). Two operating points are shown. Point 1 is defined by the load line cutting the operating locus
in the CV region, which defines the CV mode (curve A). In this mode, the power module will maintain the voltage at V
for varying load currents (determined by V÷Rl) up to IS. If the load demands a current greater than IS, the power module
S
10 General Information
switches to CC mode. CC mode (curve B) is defined by the load line cutting the operating locus in the CC region (see
Point 2). Under this condition, the power module maintains the current at IS at some voltage determined by IS x Rl.
When the power module is operated beyond either rated output, the performance specifications are not guaranteed,
although typical performance may be good. Operation in quadrant 2 is limited to about 10% of the maximum rated
positive output current. This allows the power module to sink current for more rapid downprogramming in the CV mode.
Specifications and Supplemental Characteristics
Table 1-1 lists the specifications of the power modules. Specifications are warranted over the specified temperature range.
Table 1-2 lists the supplemental characteristics, which are not warranted but are descriptions of performance determined
either by design or type testing.

Before inserting the power module in the mainframe, read the following information to determine if you need to change
any of the switch settings.
Line Voltage Switches
Figure 2-1 shows the location of the line voltage switches and the ac line fuse. The line voltage switches are shipped in
the 230-volt position. If required, use a flat-bladed screwdriver or similar tool to move both switches to the proper
position for your nominal line voltage.
Line Voltage Switch Position
110, 120 Vac 115
200, 220, 230, 240 Vac 230
Note If you change the line switch position, remember to also correct the line voltage label on the rear of the
mainframe. The mainframe contains no line voltage switches.
Configuration Switch
Figure 2-2 shows the location of the power module configuration switch. Table 2-1 indicates the functions of the switch
and the factory-default settings. If you need to change any of the settings, refer to the applicable function.
