CMLV12S24-150 Wall Industries,Inc., CMLV12S24-150 Datasheet - Page 5

• Manufacturer Part Number: CMLV12S24-150
• Description: Low Voltage Dc-dc Chassis Mount Converter 10-36 Vdc Input 24vdc Output At 6.25a Half-brick Package
• Manufacturer: Wall Industries,Inc.

Output Voltage Trim: (24V, 26V, and 28V Models)
The output is adjustable ±10% of rated output voltage. To trim the output voltage up, place the trim resistor
between the Trim and –Rs pins (Figure 4). To trim the output voltage down, 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).

Figure 4: Trim Up
Note that while decreasing the output voltage, the
maximum output current still remains at 6.25A, and
while increasing the output voltage, the output
current is reduced to maintain a total output power at
150 W.
