DC/DC converter with 4A

SLAD4.100

• Input: DC 24V

• Output: 30.55V / 4A

• AS Interface data decoupling

• For highly demanding industrial

applications

The primary switched mode DIN rail DC/DC converter SLAD4.100 specif-

ically supplies AS Interface systems with energy. The AS-Interface bus

technology allows to connect up to 62 participants to a control and to

supply them with energy with a single two-conductor cable.

When connecting slaves, the yellow AS-Interface cable offers the high

degree of protection IP67 in conjunction with the insulation displace-

ment. The communication signals of the individual network participants

are modulated onto the supply voltage. For this purpose, specific DC/DC

converter units with integrated

data decoupling are required for AS-Interface systems.
