Typical STB Power Supply 1-1 SECTION 1 GENERAL INFORMATION 1-1 DESCRIPTION 1-2 The STB Series of power supplies is designed for applications requiring extreme stability, regulation, and insensitivity to ambient temperature variations.

17、 The supply is completely transistorized (all-silicon) and is suitable for either bench or relay rack operation. The accurate programming coefficient allows the supply to be used as a 0.1% calibrator, or as a voltage reference source. It is a Constant Voltage / Current Limiting supply that will furn

18、ish full rated output voltage at the maximum rated output current or can be continuously adjusted throughout the output range. The front panel CURRENT controls can be used to establish the output current limit (overload or short circuit) when the supply is used as a constant voltage source and the V

19、OLTAGE controls can be used to establish the volt- age limit (ceiling) when the supply is used as a constant current source. 1-3 The power supply has both front and rear terminals. Either the positive or negative output terminal may be grounded or the power supply can be operated floating at up to a

20、 maximum of 300 volts off ground. 1-4 A single meter is used to measure either output voltage or output current in one of two ranges. The voltage or current ranges are selected by a METER switch on the front panel. 1-5 The programming terminals located at the rear of the unit allow ease in adapting

21、to the many operational capabilities of the power supply. A brief description of these capabilities is given below: a. Remote Programming The power supply may be programmed from a remote Location by means of an external voltage source or resistance. b. Remote Sensing The degradation in regulation wh

22、ich would occur at the load because of the voltage drop in the load leads can be reduced by using the power supply in the remote sensing mode of operation. c. Series and Auto Series Operation Power Supplies may be used in series when a higher output voltage is required in the voltage mode of operati

23、on or when greater voltage compliance is required in the constant current mode of operation. Auto-Series operation permits one knob control of the total output voltage from a master supply. d. Parallel Operation The power supply may be operated in parallel with a similar unit when greater output cur

24、rent capability is required. e. Auto-Tracking The power supply may be used as a master supply, having control over one (or more) slave supplies that furnish various voltages for a system. 1-6 SPECIFICATIONS 1-7 Detailed Specifications for the power supply are given in Table 1-1. 1-8 OPTIONS 1-9 Opti

25、ons are factory modifications of a standard instrument that are requested by the customer. A typical option is replacing the front panel voltage and current controls with ten-turn voltage and current decadial controls. The following options are available on the instrument covered by this manual. Whe

26、re applicable, detailed coverage of options is included throughout the manual. Option No. Description 06 Overvoltage Protection Crowbar: A completely separate circuit for protecting delicate loads against power supply failure or operator error. This independent device monitors the output voltage and

27、 within 10sec impose a virtual short- circuit (crowbar) across the power supply output if the preset overvoltage margin is exceeded. When Option 06 is requested by the customer, Model 6916A is attached to the rear of the power supply at the factory. Overvoltage Margin: 1 to 4 volts, screwdriver adju

28、stable. Power Requirement: 15mA continuous drain from power supply being protected. 1-2 Size: Add 5 inches to power supply depth dimension. Weight: Add 2 lbs. net. NOTE Detailed coverage of Option 06 is included in an addendum entitled, Model 6916A Overvoltage Protector. The addendum is included at

29、the rear of manuals that support power supplies that have been modified for Option 06. 28 Rewire for 230V Input: Supply as normally shipped is wired for 115VAC input. Option 28 consists of reconnecting the input transformer for 230VAC operation. 1-10 ACCESSORIES 1-11 The accessories listed in the fo

30、llowing may be ordered with the power supply or separately from the local Hewlett-Packard field sales office (refer to list at rear of manual for addresses).

32、 INSTRUMENT IDENTIFICATION 1-13 Hewlett-Packard power supplies are identified by a three-part serial number tag. The first part is the power supply model number. The second part is the serial number prefix, which consists of a number-letter combination that denotes the date of a significant design c

33、hange. The number designates the year, and the letter A through L designates the month, January through December respectively. The third part is the power supply serial number. 1-14 If the serial number prefix on your power supply does not agree with the prefix on the title page of this manual, chan

34、ge sheets are included to update the manual. Where applicable, backdating information is given in an appendix at the rear of the manual. 1-15 ORDERING ADDITIONAL MANUALS 1-16 One manual is shipped with each power supply. Additional manuals may be purchased from your local Hewlett-Packard field offic

35、e (see list at rear of this manual for addresses). Specify the model number, serial number prefix, and Stock Number provided on the title page. 1-3 Table 1-1.
