Safety Considerations
Bel Power Inc., a subsidiary of Bel Fuse Inc.
For safety agency approval the power module must be installed in compliance with the spacing and separation
requirements of the end-use safety agency standards, i.e., UL 60950-1, CSA C22.2 No. 60950-1-03, and VDE
0850:2001-12 (EN60950-1) Licensed. The SLIN-30E1Ax was tested using a 30A, time delay fuse in the
ungrounded input.
For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input
must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV.
The input to these units is to be provided with a time-delay fuse with a maximum rating of 30A in the positive
input lead.

The SLIN-30E1Ax power modules feature an On/Off pin for remote On/Off operation. If not using the On/Off pin,
connect the pin to ground (the module will be ON). The On/Off signal (V_on/off) is referenced to ground. The circuit
configuration for remote On/Off operation of the module using the On/Off pin is shown below.
During a Logic High on the On/Off pin (transistor Q1 is OFF), the module remains OFF. The external resistor R1
should be chosen to maintain 3.0V minimum on the On/Off pin to ensure that the module is OFF when transistor
Q1 is in the OFF state. Suitable values for R1 are 4.7K for input voltage of 12V and 3K for 5Vin. During Logic-
Low when Q1 is turned ON, the module is turned ON.
The On/Off pin can also be used to synchronize the output voltage start-up and shutdown of multiple modules in
parallel. By connecting On/Off pins of multiple modules, the output start-up can be synchronized (please refer to
characterization curves). When On/Off pins are connected together, all modules will shutdown if any one of the
modules gets disabled due to under voltage lockout or over temperature protection
