For applications that require meeting EMC standards, the diagrams below illustrate typi- www.micropowerdirect.com
cal connections of the MD900xRU series. Some notes on this diagram (starting with the
input circuit) are:
3. The output fi ltering components C9 & C11 are high frequency, low ESR electrolytic
1. An external fuse should be used in all power module applications. The recommended capacitors. Capacitors C10 & C12 are ceramic. Care must be taken in choosing
fuse is shown in the model chart on page 2. these capacitors not to exceed the capacitive load specifi cation for the unit. Voltage
2. To protect against voltage spikes, it is recommended that a TVS be used on the input. derating of capacitors should be 80% or above.
A suggested value is given in the tables below.
