It provides detailed guidance on installation, maintenance, and remote programming, as well as specifications for output voltage, current, and noise levels.
Manual Overview
The BK Precision VSP series high power switching DC power supplies include models VSP6020, VSP2050, VSP4030, and VSP12010, each offering 1200-watt output power with constant voltage and current modes. These units feature switch mode conversion with high efficiency and power factor correction to maintain near unity power factor. Troubleshooting involves checking for correct input connections and ensuring the unit is not overloaded. Error diagnostics are facilitated by 3-digit LED displays showing output voltage, over-voltage set levels, and current. Calibration and adjustments can be made using multi-turn potentiometers for voltage and current settings. The series supports remote operation through RS232 or GPIB interfaces, allowing for digital control with 12-bit resolution. For board-level guidance, the units provide isolated analog voltage, current, and resistance programming with built-in isolation amplifiers. Safety precautions are critical, especially when dealing with high voltage, and include using isolation transformers and adhering to safe work practices to prevent electrical shock. Regular maintenance and adherence to installation guidelines are essential for optimal performance.

Safety & Warnings
Normal use of test equipment exposes users to electrical shock dangers, as testing often involves exposed voltage. A current of 10 milliamps passing through the heart can stop most human heartbeats, and voltages as low as 35 volts can be lethal. To reduce risk, users should:
– Avoid exposing high voltage unnecessarily and remove housings only when needed.
– Turn off equipment when making test connections in high voltage circuits and discharge capacitors after removing power.
– Familiarize themselves with the equipment’s high voltage points, as high voltage may appear unexpectedly in defective equipment.
– Use insulated floor material or a large, insulated floor to stand on, and ensure work surfaces are not damp.
– Employ the “one hand in the pocket” technique when handling probes to avoid creating a ground return path.
– Remember that ac line voltage is present on some circuits even if equipment is turned off.
– Use an isolation transformer with two-wire ac power cord equipment to avoid shock hazards.
– Use only a 3-wire outlet with equipment that has a 3-wire ac power plug to maintain safety.
– B&K Precision products should not be used for direct contact with the human body or as critical components in life support devices.
– Never work alone; someone should be nearby to provide aid if necessary. CPR and first aid training are recommended.
