AV45C series converters have a 2:1 input voltage range and can accept 36-75 Vdc input. Care should be taken to avoid applying reverse polarity to the input which can damage the converter. Note: the fuse is normal blow type. Input Reverse Voltage Protection Under installation and cabling conditions where reverse polarity across the input may occur, reverse polarity protection is recommended. Protection can easily be provided as shown in Figure 2. In both cases the diode rating is determined by the power of the converter. +Vin +Vin -Vin -Vin CNT +Vin -Vo -Sense TRIM +Sense +Vo -Vin Fig.2 Reverse Polarity Protection Circuits Placing the diode across the inputs rather than in-line with the input offers an advantage in that the diode only conducts in a reverse polarity condition, which increases circuit efficiency and thermal performance. Input Undervoltage Protection The AV45C quarter-brick series is protected against undervoltage on the input. If the input voltage drops below the acceptable range, the converter will shut down. It will automatically restart when the undervoltage condition is removed. Input Filter Input filters are included in the converters to help achieve standard system emissions certifications. Some users however, may find that additional input filtering is necessary. The AV45C quarter-brick series has an internal switching frequency of 250 kHz so a high frequency capacitor mounted close to the input terminals produces the best results. To reduce reflected noise, a capacitor can be added across the input as shown in Figure 3, forming Fig.1 Pins Location ( Pin-side View ) Input Characteristic Fusing The AV45C power module has no internal fuse. An external fuse must always be employed! To meet international safety requirements, a 250 Volt rated fuse should be used. If one of the input lines is connected to chassis ground, then the fuse must be placed in the other input line. Standard safety agency regulations require input fusing. Recommended fuse ratings for the AV45C quarter-brick are shown in Table 1.

Table 2 L N ON OFF H OFF ON Open OFF ON +Vin C1 -Vin P Fig.3 Ripple Rejection Input Filter Also when a filter inductor is connected in series with the power converter input or when the input wiring is long (since the wiring can act as an inductor), an input capacitor C1 should be added. Failure to use an input capacitor under these conditions can produce large input voltage spikes and an unstable output.

The input-to-output 1500VDC isolation is an operational insulation. The DC/DC power module should be installed in end-use equipment, in compliance with the requirements of the ultimate application, and is intended to be supplied by an isolated secondary circuit.
