100% Original MTL3992 HIGH STABILITY POWER SUPPLY for strain-gauge bridges In Good Price Ready To Ship
The MTL3992 is a galvanically isolated power supply unit designed to provide an accurate and stable voltage suitable for powering bridge circuits in hazardous areas. An integral voltage sensing circuit maintains a constant and stable bridge voltage enabling bridge outputs to be measured directly. A typical use for the unit is powering up to four 350Ω load-cells in hazardous areas as part of a complete weighing system application (which may also include MTL interfaces, transmitters, and indicators).
