Puls launches redundancy module for telecoms use
Puls
YR80 24V low-loss MOSFET redundancy module
Puls has launched the YR80 24V low-loss MOSFET redundancy module for telecoms, production equipment, access control systems and signalling device applications.
Only one redundancy module is needed to build a 40A redundant system, as diodes have been replaced by MOSFET.
The low on-resistance of the MOSFET is said to cause a considerably lower voltage drop than with diodes; at 40A output current a drop of only 50mV is present between the input and output terminals, while, with traditional diodes, a drop of at least 500mV would occur.
This saves energy and reduces the heat generated, making cooling much less of a problem.
The YR80 produces losses of only 2.7W at 40A output current, including losses at the terminals.
The internal wiring and the supply circuit meaning that a heat sink is not required.
