PRODUCT OVERVIEW
The NMUSBEVALEXC is a standalone module which conveniently provides dual port USB data isolation
Power surge notication
from a single upstream port with full power (500mA) available from each downstream port. Isolation
Patents Pending
provides effective breaking of ground loops and immunity to EMI in harsh environments as found in
industrial and medical applications. Full speed (12Mbps) and low speed (1.5Mbps) are supported with
automatic switching. Input power of 5V is provided by an external adapter or system voltage rail. The
NMUSBEVALEXC has a conventional USB B type connection.
The NMUSBEVALC is a internal module which conveniently provides dual port USB data isolation from a
single upstream port with full power (500mA) available from each downstream port. Isolation provides
effective breaking of ground loops and immunity to EMI in harsh environments as found in industrial
and medical applications. Full speed (12Mbps) and low speed (1.5Mbps) are supported with automatic
switching. Input power of 5V is provided by an external system voltage rail. The NMUSBEVALC has a molex
pin header which can be mounted to a system socket holder to create a dual port USB data isolater.
All specications typical at TA=25C, nominal input voltage and rated output current unless otherwise specied.

TECHNICAL NOTES
ISOLATION VOLTAGE
Hi Pot Test, Flash Tested, Withstand Voltage, Proof Voltage, Dielectric Withstand Voltage & Isolation Test Voltage are all terms that relate to the same thing, a test
voltage, applied for a specied time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.
The NMUSBEVAL series has been recognized by Underwriters Laboratory to 250 Vrms Reinforced Insulation.
REPEATED HIGH-VOLTAGE ISOLATION TESTING
It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on
materials, construction and environment. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be
reduced by 20% from specied test voltage.
SAFETY APPROVAL
ANSI/AAMI ES60601-1
The NMUSBEVAL is recognized to ANSI/AAMI ES60601-1 and provides 1 MOPP (Means Of Patient Protection) and 2 MOOP (Means Of Operator Protection) based upon a working
voltage of 250 Vrms max, between Primary and Secondary.
UL 60950
The NMUSBEVAL series has been recognised by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250Vrms.
FUSING
The NMUSBEVAL series of converters are not internally fused so to meet the requirements of UL an anti-surge input line fuse should always be used with ratings as dened below.
NMUSBEVAL - 2.5A (125Vdc rated)
All fuses should be UL recognized and rated to at least the maximum allowable DC input voltage.
RoHS COMPLIANCE, MSL AND PSL INFORMATION
NMUSBEVAL is compatible with RoHS soldering systems with a peak reow solder temperature of 245C as per
J-STD-020D.1. The pin termination nish on this product series is Gold with Nickel Pre-plate. The series is backward
compatible with Sn/Pb soldering systems. The product has a Moisture Sensitivity Level (MSL) 3.
