Description
BK Precision 1652 – Triple Output DC Power Supplies
Display: Digital
Voltage (Variable/(Fixed)): 0-24 V/(5 V / 4 A)
Current: 0-500 mA
Designed to operate continuously at rated output
Ideal for educational instruction in an electronic lab, the 1651A and 1652 triple output DC laboratory power supplies have two 0 to 24 VDC outputs capable of supplying 0 to 500 mA, and one fixed 5 VDC output capable of supplying up to 4 A. Connect outputs in series for higher voltage or connect in parallel for higher current output (selectable via tracking mode switch). Voltage and current for variable outputs are continuously monitored on two analog (1651A) or two digital (1652) displays. These power supplies also provide reverse polarity, overvoltage, and current limiting protection.
Features and Benefits:
TRIPLE OUTPUT – Operates as three separate power supplies. Each has floating output and is completely isolated from the other two.
ONE FIXED 5V SUPPLY – 0-to-4 amp fixed 5 volt supply is ideal for use with most digital logic circuitry. Adequate current capacity for extensive circuitry.
TWO 0-24 VOLT SUPPLIES – “A” and “B” supplies are continuously variable over 0-to-24 volt range. Each supply 0. 5 amp current capacity.
UNIQUE TRACKING FEATURE – The two 0-to-24 V supplies can be operated so that the “B” supply tracks the “A” supply. Outputs can be strapped for two positive voltages with a common negative, two negative voltages with a common positive, or one positive and one negative with a neutral common.
SINGLE 0-48V SUPPLY – Series tracking feature allows use of “A” and “B” supplies as one 0-to-48 V, 0.5 amp supply.
SINGLE 0-24V 1 AMP SUPPLY- Parallel tracking feature allows use of “A” and “B” supplies as a 0-to-24 V supply with a 1 amp current capacity (through “A” output terminals).
CONSTANT VOLTAGE OR CONSTANT CURRENT – The “A” and “B” supplies provide regulated dc voltage output or regulated dc current output. Crossover is smooth and automatic.
METERING – Two, easy-to-read meters monitor output voltage and output current of the “A” and “B” supplies. Use of two meters allows simultaneous current and voltage metering when using “A” and “B” supplies in tracking or independent operation.
LABORATORY QUALITY – Excellent regulation, low ripple.
LED INDICATORS – Identify mode of operation.
PRE-REGULATOR – Limits internal dissipation for higher reliability and efficiency
ISOLATED OUTPUT – Either polarity may be floated or grounded
OVERLOAD PROTECTION – Fully adjustable current limiting (from 6% to 100% of maximum output current) for “A” and “B” supplies protects circuit under te st and the power supply
REVERSE POLARITY PROTECTION – Prevents damage to power supply from external voltage of reverse polarity.
HOOK-UP CABLES – Supplied with three sets of red and black hook-up leads.
