Analog Devices’ RS-232/RS-485 multiprotocol transceivers are the only parts in the market that allow protocol switching and allow for switching between half-/full-duplex operation and switching on/off termination resistors, both of which minimize physical user intervention when reconfiguring networks. Features include 3.3 V to 5 V operation, up to ±26 kV ESD, a logic supply pin, and small LFCSP packages. As large-scale computing applications typically require more protocols than the RS-232 and RS-485 protocols found in everyday applications, we support legacy protocols. These include V.28 (RS-232), V.35, RS-449, RS-530, RS-530-A, V.36, or X.21. Software-selectable protocol, cable termination, and data terminal equipment (DTE) or data communications equipment (DCE) configurations all provide convenient flexibility.

Transformer turns ratio testers from TRT series are DV Power instruments mainly designed for the measurement of power transformer turns ratio. Also, they measure transformer excitation current and phase shift. Special tests, such as automatic vector group detection and magnetic balance, can be performed on three-phase transformers and three-phase autotransformers.All models, except TRT03 series, have a built-in true three-phase power source, which is necessary for testing turns ratio of transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.DV Power turns ratio testers can output various test voltages for different applications. From the extremely low test voltage of 1 V AC that enables turns ratio verification of the majority of current transformers, up to the highest test voltage of 500 V AC that provides the most accurate turns ratio testing of power transformers used in power generation and transmission. By using the external booster, test voltage increases up to 5 kV AC in order to successfully test capacitive voltage transformers.All DV Power turns ratio testers have a built-in tap changer control unit. Because of that, it is possible to control the on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, the instrument and included DV-Win software can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions, and saving results. This option significantly facilitates and shortens the turns ratio testing time.TRT turns ratio testers use the same set of cables as three-phase winding ohmmeter & tap changer analyzers from the TWA series. Consequently, it enables one-time cable setup for performing eight tests:turns ratioexcitation currentphase anglemagnetic balancevector group detectionwinding resistanceon-load tap changer DVtestand demagnetization.
