IMPORTANT SAFETY INSTRUCTIONS
Safety Admonishments Definitions
Definitions of the safety admonishments used in this document are listed
under “Admonishments Used in this Document” on page 5.
General Safety
DANGER! YOU MUST FOLLOW APPROVED SAFETY PROCEDURES.
Performing the following procedures may expose you to hazards.
These procedures should be performed by qualified technicians
familiar with the hazards associated with this type of equipment.
These hazards may include shock, energy, and/or burns. To avoid
these hazards:
a) The tasks should be performed in the order indicated.
b) Remove watches, rings, and other metal objects.
c) Prior to contacting any uninsulated surface or termination, use a
voltmeter to verify that no voltage or the expected voltage is
present. Check for voltage with both AC and DC voltmeters prior
to making contact.
d) Wear eye protection.
e) Use certified and well maintained insulated tools. Use double
insulated tools appropriately rated for the work to be performed.
Voltages
AC Input Voltages
DANGER! The system the power extend converter is installed in
operates from AC input voltage capable of producing fatal electrical
shock.
DC Input Voltages
DANGER! The power extend converter operates from DC input
voltage. Although the DC voltage is not hazardously high, the input
power can deliver large amounts of current.

Vertiv |eSure™ Power Extend Converter Installation and User Manual (UM565050)|Rev. D
7
DC Output and Battery Voltages
DANGER! The system the power extend converter is installed in
produces DC power and may have a battery source connected to it.
Although the DC voltage is not hazardously high, the rectifiers and/or
battery can deliver large amounts of current.
Personal Protective Equipment (PPE)
DANGER! ARC FLASH AND SHOCK HAZARD.
Appropriate PPE and tools required when working on this equipment.
An appropriate flash protection boundary analysis should be done to
determine the “hazard/risk” category, and to select proper PPE.
Only authorized and properly trained personnel should be allowed to
install, inspect, operate, or maintain the equipment.
Do not work on LIVE parts. If required to work or operate live parts,
obtain appropriate Energized Work Permits as required by the local
authority, per NFPA 70E “Standard for Electrical Safety in the
Workplace”.
Hazardous Voltage
DANGER! HAZARD OF ELECTRICAL SHOCK.
More than one disconnect may be required to de-energize the
system before servicing.
Handling Equipment Containing Static Sensitive Components
ALERT! Installation or removal of equipment containing static
sensitive components requires careful handling. Before handling any
equipment containing static sensitive components, read and follow
the instructions contained on the Static Warning Page.

Vertiv |eSure™ Power Extend Converter Installation and User Manual (UM565050)|Rev. D

STATIC WARNING
This equipment contains static sensitive components. The warnings
listed below must be observed to prevent damage to these
components. Disregarding any of these warnings may result in
personal injury or damage to the equipment.
1. Strictly adhere to the procedures provided in this document.
2. Before touching any equipment containing static sensitive
components, discharge all static electricity from yourself by
wearing a wrist strap grounded through a one megohm resistor.
Some wrist straps have a built-in one megohm resistor; no
external resistor is necessary. Read and follow wrist strap
manufacturer’s instructions outlining use of a specific wrist strap.
3. Do not touch traces or components on equipment containing
static sensitive components. Handle equipment containing static
sensitive components only by the edges that do not have
connector pads.
4. After removing equipment containing static sensitive
components, place the equipment only on static dissipative
surfaces such as conductive foam or ESD bag. Do not use
ordinary Styrofoam or ordinary plastic.
5. Store and ship equipment containing static sensitive
components only in static shielding containers.
6. If necessary to repair equipment containing static sensitive
components, wear an appropriately grounded wrist strap, work
on a conductive surface, use a grounded soldering iron, and use
grounded test equipment.

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.

are listed in Table 3.Each kit comes with specific installation instructions.
Refer to Figure 1for an illustration of the C48/58-1000B.
Application
Applications of this product include, but are not limited to the following:
•This product could be used in applications in which the DC power is
delivered over long distances to the end load.
•The power extend converter, with its output voltage regulated at a
higher level than its input, allows the end load to be sustained for a
longer period of time during a battery discharge condition.

DC Output Ratings
1. Nameplate Rating: -58 VDC / 17.2 A, 1000 W maximum.
2. Output Voltage: Nominal -58 VDC, positive ground. Output voltage
is non-adjustable.
3. Output Current:
a) Boost Mode: 17.2 amps maximum.
b) Bypass Mode: 24.0 amps maximum.
NOTE! The power extend converter will operate in bypass mode due
to 1) a failure of the boost conversion circuitry, (2) input voltage
exceeds 58.0 VDC, or 3) output current exceeds the boost mode
rating.
4. Output Power: See Table 5.
NOTE! These values are for a single unit and may be reduced in the
end use application. Refer to the specific mounting bracket kit
instructions (see Table 3 ) for spacing and power restrictions. Use
the calculator tool that can be obtained at https://www.vertiv.com/en-
us/products-catalog/critical-power/dc-power-systems/esure-power-
extend-converter-c4858-1000/#/downloads to determine the
necessity, quantity and spacing requirement of the Power Extend
Converter based on the RRU type (or peak load), use application
(host power system), trunk and jumper cable size and length,
minimum source voltage and minimum RRU operating voltage.
5. Regulation:
a) Output Voltage Tolerance: ±0.35 VDC (at nominal input voltage
[52V to 56.5V] and 0% to 100% load).
b) Dynamic Response: Step changes in load, from 50% to 25% or
50% to 75% at 2 A / microsecond does not cause the voltage
measured at the power extend converter output to overshoot or

undershoot more than 5% of the regulated output level. The
output voltage returns and stays within the ±1% regulation band
within 4 milliseconds.(Telcordia GR-947-CORE.)
c) Overshoot/Undershoot: 1.0% maximum output voltage overshoot
at turn-on (high voltage shutdown does not activate). No
voltage undershoots at turn-off.
d) Output Voltage Accuracy: ±0.15 V (at -58 VDC and 50% load
and nominal input voltage [52V to 56.5V]).
