Programmable power supplies are digitally controlled power sources that provide accurate and adjustable levels of voltage, current, and frequency. They include a processor, voltage/current programming circuits, current shunt, and voltage/current read-back circuits. Remote sensing functions compensate for voltage drops in the load leads by providing feedback of the actual voltage at the load. Over-voltage and over-current protection modes are also available. Comparators continuously monitor the output voltage against a program reference value. If the output value exceeds the reference value, a trigger signal is sent to a silicon-controlled rectifier (SCR) across the output, shutting off the source to the load. Most programmable power supplies are subjected to extensive testing and burn-in periods to ensure long-term performance. |
Products & Services Related to Programmable Power Supplies
AC Power Sources
AC power sources provide alternating power and typically have adjustable output values for the testing of component response at various voltage, current and frequency levels.
AC-DC Adapters
AC-DC adapters accept AC input voltage directly from a wall outlet, and output DC voltage.
Current Sources
Current sources provide reliable current for electrical component testing and for powering specialized components.
DC Power Systems
DC power systems provide continuous DC power through multiple outputs. Most DC power systems include a battery backup, temperature compensation, and other features.
High Voltage Power Supplies
High voltage power supplies use linear technology to provide one or more DC outputs at voltage levels of hundreds or thousands of volts.
Medical Power Supplies
Medical power supplies produce conditioned outputs for medical devices, instruments, and equipment.
Power Rectifiers
Power rectifiers are electrical devices that convert alternating current (AC) to direct current (DC). They are an integral part of telecom rectifiers for the telecommunications industry, and in battery chargers, DC power systems, and other power system devices.
