INTRODUCTION
Overview
The eSure™ Power Extend Converter (Model C48/58-1000B, Spec. No.
1C48581000B) is a compact DC/DC converter unit which offers efficient
power conversion. It operates from a nominal -48 VDC source to provide
regulated -58 VDC to the load for continuous operation to end of battery
discharge.
The C48/58-1000B simply plugs into a load position on the system’s
distribution panel which accepts a bullet device. The bullet terminals
provide connections for DC input and the regulated DC output. The
supplied return lead is installed from the device to the panel's return bar.
The power extend converter provides several functions.
1.
Boosts the input voltage to provide a regulated -58.0 VDC to the
load.
2.
Provides overload protection with a resettable electronic over-
current switch.
3.
Contains a mechanical switch to enable and disable the output. This
switch also resets the electronic over-current protection switch.
4.
Internal fuse for fail-safe output circuit overload protection. This fuse
will blow only in the event of a failure of the device coupled with an
external fault.
5.
By-pass mode. The device will feed the input voltage directly to the
output in the following cases:
a)
Failure of the boost converter circuitry.
b)
Input voltage exceeds output voltage set point.
