UL 746E Section 19 covers requirements for conformal coatings used instead of electrical spacings to increase the dielectric withstand voltage between traces on a printed-wiring board. Paragraph 19.3 outlines a Voltage transient test to be applied to a specific test pattern allows testing to determine spacings. The Surge Generator circuit is specified in UL 746E, Figure 19.2 is contained in the MegaPulse 746E. One press of the MegaPulse 746E TRIGGER button conducts the test suite as described in UL 746E, Para. 19.3. See the schematic in the Datasheet section on this page.

The MegaPulse 1.250-12±2 ohm is our 12kV, 6kA combination tester, with a 30 second cycle time. It can produce a combination test waveform at 2 ohms from 500V to 12kV, in tolerance with EN 60060. For example, the MegaPulse 1.250/820-12±2 ohm Surge Tester is specifically designed to perform the Impulse Test on transient overvoltage limiting devices in accordance with EN 61010, Para. 14.9, Table 17 and Table 18. This tester can perform all the tests shown in Table 17 at either 2 or 12 ohms as shown in Table 18. The output is in accordance with the published waveform from 500-12000V peak (open and short circuit). The tests can be done with a 30 second or longer wait between pulses, well within the Standard requirement of 1 minute or less. A 12 ohm tap is provided for testing Category II devices in accordance with Table 18, in accordance with the Standard. The 12 ohm tap will be in accordance with the tolerances of the voltage waveform only, as allowed by the Standard. The MegaPulse 1.250/820-12±2 ohm is equipped with a relay allowing switch selected polarity output. With the switch selected polarity output, users may opt for computer control via our option TestMinder MegaPulse, or PLC guided operation with our Relay Isolated Control board. Some users may not need this level of automation in their testing, and we can accomodate them with our model MegaPulse 1.250/820-12 2 ohm. Polarity is changed by manually switching leads. Pos/neg polarity, grounded output, 500V min, 12 ohm tap, not for use with CDN. 30 sec duty cycle, &lt,30 sec. charge time. Outputs a combination waveform at 500 12kV, 2 ohms. Front panel switch allows waveform reversal (±2 ohm model only). 30 second pulse repeat rate. 12 ohm tap provided, in accordance with EN60060 (voltage waveform only). Can be controlled from PLC or LabView with Option RI (±2 ohm model only). Outputs up to 12000V peak. Virtual Impedance of 2/12 ohms. Available TestMinder for computer control of long test sequences (±2 ohm model only). Provided with NIST calibration good for one year, A2LA/17025 calibration available. 1 year warranty.

The MegaPulse Biphasic P 360J/100 can be used to test products in research and production environments. The biphasic output pulse mimics the newest defibrillator output standard but allows more repeatability and faster pulsing than a defibrillator would. The output is stable and provides the required 360J power in a production test or continuous test environment. The available autotrigger control provides very repeatable outputs which makes testing results more meaningful. The MegaPulse 360J/100 is used to prove any part which would be subjected to defibrillator pulses. The biphasic output reversal timing can be configured at the factory for any timing desired within the pulse. Output power is also configurable upon request. Output voltage is approximately 2kV, with slight variances to meet the 360J power requirement. Output may be as high as 2040V in order to provide the power required. With the available 00-MPH Monophasic waveform option, the MegaPulse 360J can also output the truncated isolation waveform of AAMI DF-1, Figure A.2 for additional testing of defibrillator leads. Outputs a biphasic waveform containing 360J power for defibrillation parts testing. Microprocessor controlled wavform reversal for accurate, repeatable waveforms. Rated for continuous operation with one minute pulse times. Customer can specify any time in the waveform for the reversal point. Available autotrigger for extremely repeatable power output pulses. Available Monophasic truncated waveform in accordance with AAMI DF.1 Fig. A.2 (Isolation) for lead testing Available TestMinder for computer control of long test sequences 1 year warranty
