9 / 10 page page date DESCRIPTION: chassis mount dc-dc converter 9 of 10 08/2009 20050 SW 112th Ave. Tualatin, Oregon 97062 phone phone 503.612.2300 fax www.v-infinity.com fax 503.612.2383 PART NUMBER: VHK200W 15. REMOTE OUTPUT ON/OFF CONTROL The converter output can be enabled or disabled through the On/Off pin. The control logic is shown in this table. A common control circuit is shown below. 16. ISOLATION The input and output of the converter are electrically isolated. If needed, an output terminal can be connected to an input terminal, resulting in the converter non-isolated. 17. INPUT FILTERING AND EMI INTERFERENCE The VHK200W converters have input capacitors that control input current ripple and the associated EMI interference. However, they have not been tested to a formal standard for conducted emissions. Additional filtering may be needed to ensure compliance to an EMI standard. Refer to FIGURE 10 (next page) for a reference circuit.
