32 Channel Optically Isolated Digital Card
104-IDIO-16 Family
-
The Model 104-IDIO-16 is a 32-channel PC/104 utility board featuring 16 optically isolated inputs and 16 optically isolated solid state outputs. The isolated, non polarized inputs may be driven by either DC sources of 3-31V (or higher by special order) or AC sources at frequencies of 40Hz to 10KHz. Optically isolating the digital inputs from each other, and from the computer, assures smooth, error-free data transmission in noisy, real-world environments. The 16 input channels are available via a 34-pin IDC type header. The fully protected solid state outputs, capable of sourcing 2A each, are inherently more reliable than electromechanical relays and give system architects a more robust product to design with. The solid state outputs are available via a 50 pin IDC type header.

OTP-Based Test System
Test System
Power electronics assemblies often cannot be tested using conventional technology for their electrical performance. Due to the adaptability of the instrumentation, the OTP concept offers an ideal platform even beyond the space requirements of several control cabinets. In order to achieve high test flexibility with different assemblies, the system was equipped with three-phase AC sources and AC loads as well as a precise three-phase power meter. DC sources and loads with different current and voltage ranges cover the test of frequent DUT operating parameters. Time-dependent voltage or current signals can be stimulated by an arbitrary generator with power amplifier. General measurements such as current, voltage, frequency, resistance can be carried out flexibly at various test points using the matrix concept. An oscilloscope with RF multiplexer is available for high-frequency measurements such as residual ripple, switching processes, etc.

Handheld Turns Ratio & Winding Resistance Tester
TWR-H Series
-
Handheld TWR-H device is DV Power single-phase instrument designed for measuring transformer winding resistance and turns ratio.The instrument has two output DC sources for measuring transformer winding resistance. The first DC source can output up to 2 A DC and is used for injecting current to the transformer’s high voltage winding. The second DC source can output up to 10 A DC and is used for testing the transformer’s low voltage winding. This is especially useful when measuring winding resistance of distribution transformers. These transformers have large turns ratio and therefore a big difference between resistances of high voltage and low voltage windings. Upon the winding resistance test, it is also possible to demagnetize the transformer core. The demagnetization process is completely automatic and safe.Together with the turns ratio, the instrument also measures excitation current and phase shift. This enables detecting transformer core or winding turns failures which cannot be spotted by measuring turns ratio only. The instrument can output test voltage up to 40 V AC for this test, but it can also output a very low test voltage of 1 V AC which is necessary for turns ratio verification of the majority of current transformers.TWR-H is powered by an internal Li-Ion battery. Up to 100 tests can be performed with a fully charged battery.
