TTi TS3022S - Laboratórny stabilizovaný zdroj s lineárnou reguláciou 30V/2A (120W)
Bench dc power supplies |




The Thurlby Thandar TS series of laboratory bench power supplies has become highly regarded throughout the world for its performance and reliability. High resolution controls enable precise setting of voltage and current levels whilst high accuracy digital meters provide clear, unambiguous readings. |
Constant voltage or constant current TS series units can operate in constant voltage or constant current mode (not TS3023 logic output). Remote sense for high current precision TS series units incorporate integrated band-gap reference diodes as the basis for stabilisation of both voltage and current. Remote sense terminals enable the precision to be maintained at high currents by eliminating the effects of connection lead resistance. Without remote sense, lead resistance of just a few tens of milliohms can seriously degrade regulation and produce misleading results. (Two cables of just 0.05W each will drop a total of 0.3V at 3 Amps) Safety and protection TS series PSUs are designed and built to meet the latest safety and EMC requirements. All outputs are fully protected against short circuits, external overvoltage and reverse voltage. |
