Easy-to-Install Current Transducer
The AT/ATR-MS Series AC Current Transducer combines a current
sensing element and signal conditioner into a single package. The
large, easy-to-install, split-core design allows for installation over
existing conductors without the need to disconnect the load, even
in applications with multiple conductors per phase. The transducers include a 4-20mA signal proportional to the AC current, a “live
zero” output to verify proper connections where the sensor output
is 4mA with no current through the sensing ring, a sensing window
that provides ample space for bus bar, single or multiple conductors, and is factory calibrated to eliminate zeo and span potentiometer adjustment.

90W AC-DC Desktop Power Supply
The new PMP92 Series of cost effective, AC-DC desktop medical
power supplies that provide 90W of continuous output power.
Units are enclosed in a 5.51 x 2.79 x 0.87 inch 94V-0 rated poly-carbonate case with an IEC320/C6 or IEC320/C8 inlet that mates
with an interchangeable cord for worldwide use. All models meet
EN55011 and FCC Class B emission limits. The PMP92 series has
a universal 90-264VAC input, choice of Class I or Class II AC inlets,
single outputs from 12-24VDC, operation up to 5000m, low safety
ground leakage current, 100% burn in, over voltage/short circuit/
overpower protection, no minimum load requirement, and an operating temperature of 0-60°C.

SMT Shunt Resistors
The LRMAP3920 series of SMT shunt resistors for current sensing
duties feature values down to 200µ and a power rating of 5W on
FR4 fiberglass circuit boards. Maximum measurable current is over
150A, and in most cases is restricted only by the current handling of
the PCB tracks. A 10W power rating may be achieved for assemblies
on thermal substrates such as direct bonded copper, ceramic, or insulated metal substrate. The resistors’ typical load life stability of ±0.5
percent, together with TCRs down to ±50ppm/°C and thermal EMFs
less than 2µV/°C, result in only a small part of the designer’s “error
budget” being consumed, enabling more design freedom elsewhere
in the circuit.

160W Green Power Adaptors
Sunpower has added a 160W version to their family of green medical
power adaptors. GSM160B complies with IEC60601-1 3rd edition,
EN60601-1-11 and ANSI/AAMI ES60601-1-11 household medical
regulations. With 2xMOPP level and an ultra-low leakage current of
below 100µA it suits BF (patient contact) medical devices. GSM160B
is boosted by an ultra-low no load power consumption below 0.15W.
These include EISA 2007/DoE Level VI, NRCan, AU/NZ MEPS, EU
ErP and CoC Version 5. It accepts a universal 80 – 264VAC input via
an IEC320-C8 Class ll inlet with no frame ground; a range of output
voltages from 12-48VDC can be specified. The adaptor has a high
operating efficiency of up to 94% and a built-in active PFC function.
