About B&K Precision 1739
The B&K Precision 1739 single-output DC linear power supply provides a constant source of DC voltage for powering and testing electronic devices in service, engineering, production, educational, and home applications requiring low current, such as 4-20mA (milliamp) loop testing and calibration. The power supply unit (PSU) has one output that provides voltage of up to 30VDC and current of up to 1 amp, and the voltage and current output can be adjusted using fine and coarse controls on the unit's front panel. Two 4-digit LED screens show current and voltage output. The PSU can be controlled directly with the front control panel or remotely through the unit's RS-232 interface (cable included). When turned on, the PSU recalls the most-recent current and voltage settings used. A 1mA adjustable current limit with 0.1mA resolution helps protect against current overload. Built-in protection against overload, short-circuit, and reverse polarity helps prevent damage to equipment and reduce risk of shock. The unit can be set to accept an input line voltage of 120V, 220V, 230V, or 240VAC.SpecificationsNumber of outputs1Maximum voltage and current outputVoltage: 30VDC; Current: 1 ampLoad regulation, + or – (% of output + offset)Voltage: 0.04% + 1mV (millivolt); Current: 0.4% +0.1mA (milliamp)Line regulation, + or – (% of output + offset)Voltage: 0.1% + 3mV; Current: 0.4% +0.3mARipple and noise (20 Hz to 20 MHz)Less than or equal to 1mV, RMS (root mean square)Ripple currentLess than or equal to 0.4mA RMSTransient response timeLess than or equal to 75 μs (microseconds)Metering resolution and accuracyVoltage: 10mV at 0.
