Saelig Company, Inc. has announced Pulsiv OSMIUM – a novel patented power electronics technology for efficiently converting AC to DC that involves charging/discharging a small storage capacitor without the need for a PFC inductor. The OSMIUM microcontroller family and supporting components can be combined with commodity flyback DC-DC converters to displace higher-cost LLC solutions, achieving an unrivalled efficiency profile. For instance, a universal input, single switch 150W flyback power supply using the Pulsiv OSMIUM design delivers 97.5% average (99.5% peak) front-end efficiency while maintaining 90% at just 2W. Pulsiv OSMIUM microcontrollers do not directly determine output power and so they can be used as a platform for any application requiring 1W up to 10kW by adjusting only three system components and connecting a suitable DC/DC converter.
Critical components in a Pulsiv OSMIUM circuit operate at low temperatures to extend their expected operating life, even under convection cooling. By regulating the flow of line current through a charging capacitor, Pulsiv OSMIUM also completely eliminates hazardous inrush current, so manufacturers of industrial power supplies and LED lighting products can simplify their designs and reduce the cost of system installation. And the technology supports Active Bridge Control, Configurable Hold-Up, X-Cap Discharge, HVDC Output Selection, a Power Consumption Indicator and Grid Failure Detection. These optional features can be selected as required to meet the needs of different end-use applications.
The PSV-AD-250-DS Development System can be used by designers to evaluate Pulsiv OSMIUM technology; connecting a suitable DC-DC converter will produce a complete power supply prototype. Full reference designs are available to showcase what efficiencies are possible when a Pulsiv OSMIUM microprocessor design is combined with a carefully selected DC-DC converter.
Pulsiv OSMIUM power electronics technology can be used to improve overall system efficiency, reduce and optimize BOM cost, and contribute towards reducing global energy consumption. The Pulsiv OSMIUM design delivers high power factor, consistently high efficiency, in an ultra-compact system topology. Made in the UK by Pulsiv, OSMIUM microprocessors are available now from their technical distributor Saelig Company, Inc.

Saelig Company, Inc. has introduced the MSR Electronics MSR86 – a compact, reusable temperature data logger that is equipped with an external sensor for covering the range of -100 to +150degC to allow continuous monitoring of storage and shipping temperatures for perishable goods. A built-in multifunction LCD display shows the current temperature reading as well as minimum, maximum, and average values, the status of the logger and the alarm condition, as well as the battery charge level. The MSR86 logger is tamper-proof and records encrypted, password-protected measurements for compliance with 21 CFR Part 11 guidelines. The logger’s accuracy is documented by a traceable calibration certificate available in its internal memory. The MSR86 is DIN12830 and 21 CFR Part 11 compliant and meets US Food and Drug Administration (FDA) regulations for the storage and transport of chilled and frozen foods, as well as those of the EU.
There are many situations where it is imperative to maintain ambient conditions below a specified temperature to avoid spoilage or damage. The MSR86 is has been specifically designed to monitor the extremely low temperatures required during the transportation and storage of perishable products such as pharmaceuticals, enzymes, tissues, organs, vaccines, biological products, specimens, clinical materials and other sensitive products that require dry ice shipping. With its upper range of 150degC, the MSR86 data logger can also measure and record continuous high temperature profiles, such as found in ovens, autoclaves, and sterilizers.
Using the USB interface, the recorded measurement data can be easily transferred to a PC. After halting the data recording, a PDF report of the recorded measured values can be generated, which can be saved for documentation purposes. The report includes a graphical view of the temperature curve, a table of the measured values, and a statistical view of minimum, maximum, and average values, etc.
Made in Switzerland by MSR Electronics GmbH, specialists in designing miniaturized dataloggers for a broad range of uses, MSR86 loggers are available from Saelig, their US technical distributor.

Saelig Co., Inc. has introduced the NanoRanger® NR-01 – an affordable, highly accurate 3.5-digit DC ammeter designed for accurately measuring very low currents. With automatic dynamic ranging (9 ranges across 8.5 decades), NanoRanger® measures currents from 1nA up to 800mA with a maximum resolution of 10pA. Each instrument is supplied factory calibrated, eliminating the requirement for high-cost precision components in the design, and thus keeping the purchase price low. The current is measured with a 12-bit ADC which is oversampled and automatically averaged to produce a 16-bit result. Samples are taken every 170uS. Readings are shown every 300mS, built up from 180 averaged samples to eliminate line noise (both 50 Hz and 60 Hz). An alternative “Fast Sample” Mode can sample at 150 measurements per second.
The backlit 11-digit 128 x 64 LCD display provides a wealth of information for current readings; for instance, mA, uA, nA, and pA are all on one line. A Running Average reading (current and time elapsed) allows the user to measure power consumption of specific events, such as radio transmissions. The Range Coverage Bar shows the ranges covered during the measurement; it can be “bracketed” or limited to just one range. A signal-to-noise ratio display shows how much noise, or AC, is present on the current signal. Minimum and maximum ranges can be adjusted to limit the auto-ranging, or fixed at a single range.
Challenges arise when trying to measure the power consumption of low power circuits operating in offline or standby mode. Typically, current consumption falls into the nA or pA ranges that are beyond the capability of most DMMs, but the NanoRanger® measures accurately into these ranges. A 6.5 digit DMM with 1nA resolution may only have a lowest range of 2.000000mA, and the absolute accuracy may only be +/- 500nA. The NanoRanger® has selectable ranges for every decade of measurement.
NanoRanger® is designed with a fully isolated USB interface for device control and data export. Being fully isolated means that a USB connection will not adversely affect the measurements.
Low Burden Voltage (<0.05V) on all ranges. User-configurable Auto Power-off timer. 5.8” x 3.6” x 1.2”; 7 oz. Measure leakage currents over time. Understand and manage IoT power budgets. Two AA batteries allow 150 hours of operation
As engineers strive for more efficiency from new and existing products, the measurement of current consumption of devices is becoming more critical. One of the challenges in working with low power analog and digital circuits is the problem of burden voltage – the voltage drop caused by current flowing through a current measuring device that uses an internal shunt resistor network, common in most DMMs. The NanoRanger® has been designed specifically to minimize burden voltage to less than 50mV when taking low power current measurements. A large burden voltage can affect the circuit being measured, corrupting the measurement. For this reason, it is desirable for burden voltage to be kept as low as possible.
NanoRanger is designed by UK-based AltoNovus, which specializes in designing and building low power products. Aimed at the low power development community, including IoT and energy harvesting technologies, NanoRanger is available now from Saelig Company, Inc. – http://www.saelig.com.
