Power supply unit for calibrators/sensors БП-516
Category: Power supplies
| Использование | Functional equipment |
The power unit consists of a reducing transformer and two independent channels each of which is a linear stabilized D.C. power supply source. Output voltages 12 and 24 V. The channels are galvanically separated and are protected from overload and short circuit. Simultaneous overload or short circuit in two channels does not lead to the power supply unit failure.
The power supply unit contains the resistance of 430 Ohm to simulate the sensor load.
By the customer’s order the company can manufacture power supply units with other output voltages and load currents as well as with different levels of protection circuit tripping, current and short circuit current limit values.
