This test is known as a ‘High Pot Test‘, ‘Flash Tested‘, ‘Withstand Voltage‘, ‘Proof Voltage‘, ‘Dielectric Withstand Voltage‘& ‘Isolation Test Voltage‘. All isolated Power Modules are 100% production tested at their stated isolation voltage. This is 1.5 kVDC for 60 seconds. The isolation test voltage indicated in this data sheet is for voltage transient immunity only. It does not allow this part to be used within a safety isolation system. The module will function properly with several hundreds of volts applied continuously across the isolation barrier, however surrounding components must be individually analyzed to ensure proper insulation. Isolation measures must be taken in to account to prevent any user-accessible circuitry from causing harm. DIELECTRIC TEST SETUP (HIGH POT TEST) Connect all input and output terminals together (see figure below) before connecting the supply voltage. When testing, set the cut-off current to 1mA. VIN 2 +VIN +VOUT 4 VOUT Module VINGND 1 -VIN -VOUT 3 VOUTGND Supply Parameters Supply Device: Current limit set 1mA, test voltage 1500 VDC, test time 60s. REPEATED HIGH-VOLTAGE ISOLATION TESTING A repeated high voltage test of a barrier component degrades its isolation capabilities. The primary and secondary windings within this transformer are enameled (coated) but do not possess additional isolation. Typically, parts can withstand multiples of their stated test voltage and still perform optimally. The magnet wire coating can degrade over time due to chemical reactions that occur at high voltages. We recommend keeping high voltage isolation testing to a minimum to better protect the isolation between the windings. If repeated high voltage isolation testing is required, consider reducing the voltage by a significant amount e.g. 20% from the test voltage stated within the datasheet These safety concerns are equally applicable to components that utilize functional isolation beyond wire coating (i.e. physical barriers or spacing).

All modules have an integrated IC, rectifying diodes, input and output capacitors and a transformer. Since there is no feedback path from the output to the input, the duty cycle is fixed at 50% and is independent of the load (zero load to full load). The output voltage is unregulated and defined by the turns ratio of the transformer. PROTECTIVE FEATURES Due to the structure of the 1779405x11 MagI3 C power modules, the following protective features are NOT implemented: • Over temperature protection (OTP) • Overcurrent protection (OCP) • Output overvoltage protection (OVP) • Input overvoltage protection • Input reverse polarity protection Note: To protect the source and the MagI3 C power module in abnormal conditions (e.g. secondary side overload or short circuit) a primary side input fuse (slow blow) is recommended.

Power Isolation VIN 2 FISM +VIN +VOUT 4 Viso DC DC Supply DC 1 -VIN -VOUT 3 Signal Isolation RS485 Transceiver RXD 8 Viso R RE/ CON Viso 1 Rx 2 DE 3 D 4 B 7 A 6 Tx Viso Communication Line 5 TXD MCU PC Communication Card To set up an isolated communication, different functional units are required. The data for the RS485 transceiver is provided by the Micro Controller Unit (MCU), which in turn receives data from the RS485 transceiver. With the use of optocouplers the signal isolation unit can achieve galvanic isolation of the signals. A power isolation unit - a DC/DC converter power module - attains galvanic isolation of the grounds between the signal isolation unit and the transceiver unit. The main benefit of galvanic power isolation is the prevention of faults than can propagate from the supply voltage through the bus and disturb signal lines.
