GENERAL INFORMATION

INTRODUCTION

This manual describes all models in the Agilent E361xA 60W Bench Power Supply family and unless stated otherwise, the information in this manual applies to all models.

SAFETY REQUIREMENTS

This product is a Safety Class I instrument, which means that it is provided with a protective earth ground terminal. This terminal must be connected to an ac source that has a 3-wire ground receptacle. Review the instrument rear panel and this manual for safety markings and instructions before operating the instrument. Refer to the Safety Summary page at the beginning of this manual for a summary of general safety information. Specific safety information is located at the appropriate places in this manual.

This power supply is designed to comply with the following safety and EMC(Electromagnetic Compatibility) requirements

INSTRUMENT AND MANUAL IDENTIFICATION

A serial number identifies your power supply. The serial number encodes the country of manufacture, the date of the latest significant design change, and a unique sequential number. As an illustration, a serial number beginning with KR306 denotes a power supply built in 1993 (3=1 993, 4=1994, etc), 6th week manufacture in Korea(KR). The remaining digits of the serial number are a unique, five-digit number assigned sequentially.

If a yellow Change Sheet is supplied with this manual, its pur- pose is to explain any differences between your instrument and the instrument described in this manual. The change sheet may also contain information for correcting errors in the manual.

OPTIONS

Options 0EM, 0E3 and 0E9 determine which line voltage is selected at the factory. The standard unit is configured for 115 Vac ± 10%. For information about changing the line voltage setting, see paragraph "INPUT POWER REQUIREMENTS", page 1-6.

ACCESSORY

The accessory listed below may be ordered from your local Agilent Technologies Sales Office either with the power sup- ply or separately. (Refer to the list at the rear of the manual for address.)

Agilent Part No. Description

5063-9240 Rack Kit for mounting one or two 3 1/2" high supply in a standard 19" rack

The rack mount kit is needed for rack mounting of all models in the Agilent E361xA power supply because these supplies have molded feet.

DESCRIPTION

This power supply is suitable for either bench or rack mounted operation. It is a compact, well-regulated, Constant Voltage/Constant Current supply that will furnish full rated output voltage at the maximum rated output current or can be continuously adjusted throughout the output range. The out- put can be adjusted both locally from the front panel and remotely by changing the settings of the rear panel switches (See paragraph "REMOTE OPERATING MODES", page 1-9). The models in this family offer up to 60 watts of output power, with voltage up to 60 volts and current up to 6 amps as shown in Table 1.

The front panel VOLTAGE control can be used to establish the voltage limit when the supply is used as a constant cur- rent source and the CURRENT control can be used to estab- lish the output current limit when the supply is used as a constant voltage source. The supply will automatically cross over from constant voltage to constant current operation and vice versa if the output current or voltage exceeds these pre- set limits.

The front panel includes an autoranging (E3614A single- range) digital voltmeter and a single-range digital ammeter. Two 3 1/2 digit voltage and current displays accurately show the output voltage and current respectively. The output rat- ings for each model are shown in the Specifications and Operating Characteristics Table.

The OVP/CC SET switch is used to check the OVP trip volt- age and current control set value. When pressing this switch, the voltage display indicates the OVP trip voltage and the cur- rent display indicates the current control set value.

The power supply has both front and rear output terminals. Either the positive or negative output terminal may be
