Case Material: Plastic non-conductive. UL-94 HB flammability rating.
Dimensions: 2.40” Length x 1.85” Wide x 0.925” High
(60.96mmx46.99mmx23.495mm)
Cable Length: Maximum cable length is 5 meters on each side.
Connectors: High retention USB Type A (x 1) and USB Type B (x 1)
connectors with minimum withdrawal force of 15 Newton’s
Data Rate: Selectable full-speed 12Mbps (Default) or low-speed 1.5Mbps.
Transient Protection: Transient Voltage Suppressors are applied at both
the PC and target device ports. The metal cable shield is connected to
signal GND though a ferrite.
Power LED - Constant ON if power is on and unit is OK. Blinking ON/OFF
indicates unit is in current limit mode (>137mA) and the connected
device is drawing too much power.
Safety Approvals (All Pending): CE marked (EMC Directive
2004/108/EC), UL Listed (UL508, ANSI/ISA 12.12.01, 2007), cUL Listed
(Canada Standard C22.2, Nos. 142-M1987 and 213-M1987)
Electromagnetic Compatibility (EMC) -
Minimum Immunity Per European Norm EN61000-6-2:2001:
Electrostatic Discharge (ESD) Immunity: 4KV direct contact and 8KV
air-discharge to the enclosure port per IEC61000-4-2.
Radiated Field Immunity (RFI): 10V/M, 80 to 1000MHz AM and
900MHz keyed carrier, per IEC61000-4-3.
Electrical Fast Transient Immunity (EFT): 2KV to power, and 1KV to
signal I/O per IEC61000-4-4.
Conducted RF Immunity (CRFI): 10Vrms, 150KHz to 80MHz, per
IEC61000-4-6.
Surge Immunity: 0.5KV per IEC61000-4-5.
Emissions Per European Norm EN61000-6-4:2001
Radiated Frequency Emissions: 30 to 1000MHz per CISPR11 Class A
WARNING: This is a Class A product. In a domestic environment, this
product may cause radio interference in which the user may be
required to take adequate measures.
Power Supply: Standard 5VDC power provided from the USB host
computer up to 120mA of current.
Current Limit: Isolator is equipped with a 200mA input limiter to isolator
and this corresponds to ~137mA out. Once limit is reached, power will
open and retry momentarily, repeatedly until the current draw is less
than 200mA.
Isolation: USB power and data circuits are isolated from each other for
common-mode voltages up to 250VAC, or 354V DC off DC power
ground, on a continuous basis (will withstand 1500VAC dielectric
strength test for one minute without breakdown). Complies with test
requirements of ANSI/ISA-82.01-1988 for voltage rating specified.
Operating Temp: -40C to +70C (-40F to +149F).
Relative Humidity: 5 to 95%, non-condensing.
