Chapter 1 General Information

Description

The HP E3633A and HP E3634A DC power supplies feature a combination of programming capabi lities and linear power suppl y performance that makes them ide al for power systems applic ation s. T he power s upply i s pr ogrammable l ocall y from th e front panel or remote ly over the HP-IB and RS-232 int erfaces. This power s upply has two ranges, allowing more voltage at a lower current. An output range needed is selected from the front panel or over the remote inte rfaces.

Operational features include:

• Dual range of single-outpu t: 8V/20A and 20V/10A (HP E3633A), 25V/7A and 50V/4A (HP E3634A)

• Cons tant voltage (CV) or constant current (CC) operati on

• Overvoltage protection (OVP ) and ove rcurrent protection (OCP)

• Three storage locations (1 to 3) for user-defined operating states

• Automatic turn-on self-te st

• Remote sensing for load voltage at the front or rear panel termi nals

• User cal ibration from the front panel or over the remote interfaces

The front panel operation permits:

• Easy-to-use of knob control

• Output range selection

• Enabling or disabling OVP and OCP features

• Se tting the OVP and OCP trip levels

• Clear ing OVP and OCP conditions

• Se tting and displaying the voltage and curre nt limit values

• Saving and recalling operating states

• Returning the power supply to local mode from remote interface mode

• Retrieving/Scrolling error messages on the dis play

• Calibrating the power supply, including changing the calibration s ecure code

• Configuring the power supply for remote interfaces

• Enabling or disabling the output

Chapter 1 General Information

Description

When operated over th e remote inte rface, th e power supply can be both a liste ner and a talker. Using an external controller, you can instruct the power supply to set the output and to send the s tatus data back over the HP-IB or RS-232. Capabilities include the following feature s:

• Voltage and current programming

• Voltage and current readback

• Present and stored status readback

• Prog r ammi ng syntax error detection

• Complete self-test

The front-panel VFD (Vacuum-Fluorescent Dis play) include s:

• Displaying actual values of output voltage and current (meter mode)

• Or displaying the limit values of voltage and current (limit mode)

• Chec king the operating status from the annunciators

• Checking the type of error from the error codes (messag es)

Connections to t he power supply ’ s outpu t and to chas sis ground a re made to binding posts on the front panel and to the rear output terminals.

Warning Floating the power supply output mo re than ±60 Vdc from the chassis presents an

electric shock hazard to the operator . Do not float the outputs more than ±60 Vdc when metal shorting bars without insulat ion are used to connect the (+) output to the (+) sense and the (-) output to the (-) sense terminals.

Chapter 1 General Information

Description

Warning Outputs can be float ed to maximum of ±240 Vdc provided that the metal short ing bars

without i nsulation are eith er replaced wi th ins ulated cond uctors or they are remove d from the terminals so there is no operator access to the output conductors without insulation. All fie ld wiring insulation must be adequate for the voltage present.

The power supply is shipped with a detachable , 3-wire grounding type power cord. The ac line fuse is an extra ctor type on the rear panel. The power supply can be calibrated from the front pa nel direc tly or with a c ontroller ove r the HP-IB or RS-232 interface using calibration commands. Correction factors are stored in nonvolatile memory and are used during output programming. Calibration from the front panel or a control le r eli minat e the need to remov e the top c over or even t he ne ed to remove the power supply from your system cabinet. You can guard against unauthorized calibration by using the “Secured” cal ibration protection function.

Note The power supply’s OVP cir cuit con tains a crowbar SCR, wh ich eff ectivel y shorts the

output of the power supply whenever the overvoltage condition occurs. If ex ternal voltage s ource such as a batte ry is conn ected across the output, and the overvolt age condition inadvertently occurs, the SCR will continuously sink a large current from the source; poss ibly damaging the power supply. To avoid this a diode must be connected in series with the output as shown in Figure 3-1 on next page.
