FLEXIBLE ELECTRICAL CENTER

Description

The Flexible Electrical Center (FLEC

) is a configurable power

distribution module for the heavy transportation (OTB) market. It
accommodates circuit protection components in a compact, sealed
footprint. Your custom electrical schematic is programmed into the
FLEC

to create a simple “plug-and-play” system.

Each program is reviewed by Littelfuse for proper ratings, thermal
loading, and application. The FLEC

mates to an industry standard

connection system to provide a robust solution for heavy duty
environments.

Features and Benefits

Cover:

Twist-on cover design allows for single-hand
installation and removal

PCB:

Multi-layer board allows for custom circuit
configurations

Base:

Includes vent for pressure equalization

High Component Density:

Accepts multiple component footprints (i.e.
MINI

, JCASE

, PCB-mount, etc.) in one

package; PCB-mount components can be
installed directly to PCB (i.e. diodes, resistors,
relays) for space and cost savings

InputProtection:

MEGA

fuse can be installed across M8 input

studs to protect multiple circuits in FLEC

;

Additional MEGA-FLEX holder can be
interlocked to FLEC

for added fuse protection

Accessories:

Fuse puller included in cover

Input stud caps provided (red and black)

Spare MINI

fuse positions available in cover

Cover tether included
