Informazioni

The B & K-Preciskm Model 1635 DC Power supply is a high quality, general purpose dc power source. It provides 0-30 volts dc output, adjustable with both coarse and fine voltage controls for precise settability. The current output is 0-3 amps. A three station pushbutton assembly allows the large panel-mounted LED meter display to monitors either the output current, output voltage, or a voltage (up to 199*9 volts) applied to the external metering inputs. LED's indicate voltage or current metering. The Model 1635 exhibits excellent regulation and low ripple characteristics. The circuit design incorporates a pre- regulator, which greatly reduces internal power dissipation at low output voltages. The styling is both attractive and functional. The mechanical configuration conserves bench space and allows for easy portability. This instrument may be used in constant voltage or constant current applications. The crossover from constant voltage to constant current modes is smooth and automatic. LED’s indicate the "CV" (constant voltage) or "CC" (constant current) mode of operation. In constant voltage applications, a current limit may be preset. When load variations cause the current to reach the preset limit, the unit then regulates output current rather than output voltage. Current limits are adjustable from 5% to 100% of maximum. In constant current applications, the maximum voltage may be preset. When load variations cause current to drop below the regulated value, the unit reverts to regulated voltage operation at the preset value. Reverse polarity protection prevents accidental damage to the Power supply from improper connection to an external voltage, and current limiting protects the equipment being powered, as well as the Power supply. The output is isolated from chassis and earth ground, which permits full flexibility of connections. When needed, the (+) or W polarity may be strapped to ground, or either polarity may be floated to an external voltage. Two supplies may be connected in series as a 0-to-60 volt power source, or two supplies may be connected in parallel, with suitable balancing resistors, for up to twice the output current. This Power supply is well suited for a wide variety of electrical and electronics applications, including service shops, engineering labs, production testing, school laboratories, and home use by hobbyists. 0-30 VOLTS Continuously variable over 0-to-30 volt range with coarse and fine controls. 0-3 AMPS 0-to-3 amp current rated for continuous duty at full output current. LABORATORY QUALITY Excellent regulation, low ripple. CONSTANT VOLTAGE OR CONSTANT CURRENT Provides regulated dc voltage output or regulated dc current output. Crossover is smooth and automatic. LED DISPLAY A large, easy-to-read LED 3-1/2 digit display monitors output voltage, output current, or an external voltage and provides good visibility in bright or low light. Meter allows resolution of 0.1 volt or 0.1 amp. EXTERNAL VOLTMETER FUNCTION Front panel input jacks allow built in meter to be used to measure external DC voltages of up 199.9 volts. I-ETH INDICATORS Act as pilot light and identify mode of operation and metering. PRE-REGULATOR Limits internal dissipation for higher reliability. ISOLATED OUTPUT Either polarity may be floated or grounded. OVERLOAD PROTECTION Fully adjustable current limiting (from 5% to 100% of maximum output current) protects circuit under test and the power supply. REVERSE POLARITY PROTECTION Prevents damage to Power supply from external voltage of reverse polarity. STYLING Modern functional styling. Configuration conserves bench space and aids portability. Logical, convenient layout of controls. HOOK-UP CABLES Supplied with red and black hook-up leads.
