PONOVO, as the leading power system testing solution provider, have launched plenty of IEC61850 digital testing tools, not only digital relay test set, but also MU test set, multi-functional analyzer, 24 hours online monitoring and analyzing system, etc so that users could have suitable testing equipment for the digital substation commissioning and testings.

  • Integrated Gas Alarm & Control System

    MCX-32 - Teledyne Gas & Flame Detection

    The MCX-32 controller features a flexible design that allows the user to customize a system by choosing from a selection of individually addressable field devices or use addressable input and output modules. Detcon’s full range of gas sensors (purchased separately) can be used to create a gas detection system consisting of toxic gas, combustible gas, and/or oxygen deficiency. A wide range of field devices such as liquid level, temperature, pressure, flow, etc., can also be configured for input to the control system. Four standard I/O modules are available: a 4-channel 4-20mA input module (DA-4), a 4-alarm relay output module (RL-4), a 4-channel 4-20mA output module (AO-4), and a 4-relay contact input module (DI-4). I/O modules are din-rail mounted and stackable allowing for seamless system expansion. The I/O modules may be mounted within the main system enclosure or in separate enclosures suitable for the area classification where installation will occur. In many cases using distributed I/O nodes can significantly reduce wiring and installation costs.

  • CTL503

    Electron Plus

    The CTL503 Curve Tracer is a low-cost transistor (BJT and FET) computer controller curve tracer. Unlike other simple curve tracing units the CTL503 is designed to measure devices to 100V and upto 3A. Four collector resistors (relay selected) allow the user to test the smallest of BJT’s and FET’s as well as extracting meaningful curves from larger TO3/TO247 packaged devices. Limits on both peak test voltage and peak test current can be easily set to prevent exceeding device parameters.Pulse testing (80us/300us) is used to minimise device heating and to ensure the CTL503 can be powered via USB. This may be disabled for smaller parts.Connected and powered via USB and running our own free software the CTL503 is easily configured using a built in wizard (for quick results), or the user can adjust every instrument parameter to suit. Works with EPIC 21.010 and above.Users can save data from runs, as well simply grab images directly from EPIC.Connections are made to the DUT (device-under-test) with the built-in colour coded test leads with crocodile clips.
