Nortelco Electronics har fått ny webside og webshop
Nortelco Electronics AS ble Adeptor AS fra 1. januar 2022, men dine kontaktpersoner er de samme! Endringen gjelder områdene Elektronikk og Automasjon, og vi har fått ny webside:
Acquired from many years of marketing experiences and cumulative results, Chroma 13350 is the newest generation of Automatic Transformer Tester that not only retains the merits of old 3250 model but also has many new functions including the combination of measurement unit and scan box to reduce measurement error caused by long wire, C.T. test fixture and 80/20 channels scan box support, USB interface for test conditions back-up, LAN communication interface, separate setting of test frequency/voltage/speed, Fail Lock function and Auto Test. It solves the performance and quality problems as well as human errors occurred on production line for the transformer industry today.
For instance: To reduce human er ror s on production line, the13350 Fail Lock function is able to lock the defect DUT (Device Under Test) when the test is done to prevent it from flowing out accidently. In order to cut down the time for placement, the 13350 Auto Test function can conduct test directly without pressing the trigger key. In addition, the 13350 adopts the design of dual CPU to increase the test speed by processing the measurement and display units simultaneously.
The compensation function of 13350 can do OPEN/SHORT for individual channel to solve the errors due to different layout on various fixtures.
13350 provides 20Hz-200kHz test frequency and scan test items to cover low voltage test parameters for various transformers including Inductance (L), Leakage (Lk) , Turn-Ratio, DC Resistance (DCR), Impedance (Z), Stray Capacity (C), Quality Factor (Q), Equivalent Series Resistance (ESR), Pin Short (PS), Winding Phase (PH) and Balance.
Applicable Test Options for Selection A133502 20 Channels Scan Box
13350 uses split screen that allows the measurement unit to integrate the 20 channels scan box without using any connecting wires to reduce measurement errors. Furthermore, the 20 channels scan box has external standard test function that can perform verification test directly without any act of disassembly.
A133505 80 Channels Scan Box
13350 along with 80 channels scan box can mainly offer three different applications:
1) RJ-45 & LAN Filter test solution that can test up to 80 pins one time.
2) Transformer automation solution that can place 4 transformers on one carrier for scan test simultaneously.
3) Island-type production line planning that provides a time division multiplexing module to increase the equipment utilization rate.
A133506 C.T. (Current Transformer) Test Fixture
When the 13350 works with A133506 C.T. Test Fixture, it can measure the turns, inductance and DC resistance easily and rapidly by putting in the C.T. directly.
