For these models, IOUT1 + IOUT2 must be < 250 mA. 2. For these models, IOUT1 + IOUT2 must be < 143 mA. 3. Output power for dual output models is defined as: POUT = VOUT1 x (IOUT1 + IOUT2). 4. Output voltage accuracy is specified at full load & VIN = 115 VAC.. 5. Line regulation is specified for VIN = 85 to 264 VAC. 6. Load regulation is specified for IOUT = 10% to 100%. 7. It is recommended that a fuse be used on the input of a power supply for protection. For the MCP-02x series, a 1.2A slow blow fuse should be used.

Mains connected components/equipment may be subjected to a wide variety of surge/transient line disturbances. Input line disturbances are covered by the international standards EN-61000-4-2,3,4,5. The MCP-02x series is designed to meet the requirements of EN 61000-4 as shown on page one of this datasheet. For applications that require a higher level of immunity to line disturbances, the addition of external protection components (as shown in the diagram above) may be sufficient. Contact the factory for more information. The MCP-02x operates in constant voltage mode (the same as most AC/DC power supplies) to the point where the maximum output current ratings shown in the tables above are exceeded. When this happens, the typical constant voltage regulated supply will go into current limit and shut down. Unlike conventional current limited designs, the MCP-02x cannot be overloaded. As shown in the graph above, the unit will switch to constant power mode and will continue to supply power to the load. Mechanical Dimensions This transition from “constant voltage mode“ to “constant power mode” makes the MCP-02x especially suitable for applications where current limited designs require “oversizing” the power source to avoid start-up issues. They are well suited for applications that include driving or charging: • • • • • • • Pin Connections Mechanical Relays Solenoids Super Caps LEDs High Capacitive Loads Solid State Relays Op Amp Drivers Output 1 (VO) is voltage regulated until it reaches the “current limit” level. At this point, it transitions to constant power mode. This output cannot be overloaded.
