CMLV12S12-150 Wall Industries,Inc., CMLV12S12-150 Datasheet - Page 5

• Manufacturer Part Number: CMLV12S12-150
• Description: Low Voltage Dc-dc Chassis Mount Converter 10-36 Vdc Input 12vdc Output At 12.5a Half-brick Package
• Manufacturer: Wall Industries,Inc.

Output Voltage Trim: (5V, 12V, 15V, and 20V Models)
The output is adjustable ±10% of rated output voltage. To trim the output voltage down, place the trim resistor
between the Trim and -Rs pins (Figure 4). To trim the output voltage up, place the trim resistor between the Trim
and +Rs pins (Figure 3).
The value of the trim resistor with respect to the desired output voltage (Vo) can be derived from the following
formulas, or looked up on the trim table (Table 2).

Note that while decreasing the output voltage, the
maximum output current still remains at 12.5A,
and while increasing the output voltage, the output
current is reduced to maintain a total output power
at 150 W.
