FUNCTION
FRONT PANEL (See Figure 2-1.)
A-C line indicator Lights to indicate unit turned on and a-c power applied.
LCD 2 x 16 character Liquid Display with LED backlight. Shows voltage, current
mode, settings, menu, program, etc.
Keypad 24 keys used for local operation of the power supply; Refer to Table 3-2 for
details.
POWER circuit breaker Circuit breaker used to turn unit on and off.
Output jack Provide front panel access to d-c output of power supply.
REAR PANEL (See Figure 2-2.)
IEEE 488 PORT 24-pin GPIB connector used to connect to GPIB bus (see Table 2-2 for pin
assignments).
STATUS AND REMOTE ON/OFF PORT Notifies host computer either that a-c input is not present or a major failure of
power supply has occurred and allows remote on/off control of the unit (see
Table 2-3 for pin assignments).
RS 232 PORT 8-pin connector telephone jack type used to connect to RS 232 bus. Adapter
cable kit (see Table 1-5) converts to 9-pin jack (see Table 2-4 for 9-pin assign-
ments).
EXTERNAL TRIGGER PORT 4-pin connector used to restore previously stored settings or to shut down the
output (see Table 2-5 for pin assignments). NOTE: Mating connector is a 3-pin
plug.
OUTPUT TERMINALS barrier strip TB1
(See NOTE 1.)
Provides Power Supply output connection points. (See Table 2-6 for terminal
assignments)
V PROG terminal strip TB2
(See NOTE 1.)
Provides input/output signals for analog programming of output voltage or volt-
age limit. (See Table 2-7 for terminal assignments.)
I PROG terminal strip TB3
(See NOTE 1.)
Provides input/output signals for analog programming of output current or cur-
rent limit. (See Table 2-8 for terminal assignments.)
AC SELECTOR switch Used to select between nominal input line voltage of 115 V a-c or 230 V a-c.
AC INPUT connector Provides a-c source power to unit.
Terminal Drawer Closed detector
(see NOTE 2.)
Provides protection when Terminal Drawer is open by tripping the a-c circuit
breaker to off.
NOTES 1. Accessible by loosening two captive screws and pulling out terminal drawer, and removing protective insulator (see
Figure 2-2).
2. The Terminal Drawer detector (located on PC board A3) and the a-c circuit beaker function as an interlock switch.
