Power Supply Targets Isolation Amplifiers and Signal Conditioners
The Epsitron 787-2852 power supply is designed for isolation amplifiers and signal conditioners. In particular, it shares a common profile with Jumpflex 857 and 2857 Series signal conditioners so that output voltage can be directly commoned to the conditioners without the need for additional wiring. Its nominal output voltage may be 0 V or 24 Vdc with a capacity of 24 W and an output current of 1 A. The nominal input voltage ranges from 100 to 264 Vac at frequency ranging from 47 to 63 Hz. Pluggable picoMAX female connectors enable pre-wiring. In addition to integrated short-circuit protection, it is no-load proof and includes an integrated redundancy diode to ensure power transfer when supplies are connected in parallel.

Conductive Digital Ink Targets 3D-Printed Electronics
Designed for inexpensive inkjet printing technologies and low-temperature sintering applications, Sicrys 150TM-119 is a conductive digital ink that uses single-crystal silver nanoparticles in triethylene glycol monomethyl ether (TGME). With silver loading as high as 50% w/w, its conductive behavior and workability makes it useful in 3D-printed electronics. Its viscosity is as low as 34 cP and surface tension is 30 dyne/cm, as determined by the Du Noüy Ring Method. The ink has a long shelf life and can be used to create printed patterns. It adheres to a wide range of substrates, including Indium tin oxide, glass, PET and Kapton, even in humid and aqueous environments.

Heavy-Duty Electric Press Brake Machines Small Parts
The Goform line of all-electric press brakes targets small parts that may be thinner than 0.25-in. and weigh less than 50 lbs. It can apply 40 tons of force and leverages high resolution incremental encoders to ensure ram repeatability for accurate shape forming. It has a 10-in. stroke and a 17-in. open height for jobs requiring tall tools and adapters. Its heavy-duty frame allows for multi-shift operation and full tonnage with minimal deflection, while the 6-axis backgage enables accurate machining of complex shapes. The drive system uses satellite roller-screw actuators to reduce heat and wear over numerous cycles.
The unit can be moved with a forklift or overhead crane. It has a small footprint and will function without requiring any attachment to the floor. In addition, it can be configured to American, WT/New Standard, and European tooling styles. The holder uses a full-length clamp to allow the use of segmented dies anywhere along the length of the bed. It uses a PC-based control system.

Actuators Demonstrate Low Surface Run-Out
SHA-CG rotary actuators feature a compact, hollow shaft for versatility in many different designs. With a surface run-out of less than 10 microns, positional accuracy is more than 1 arc-minute and repeatability is ±5 arc-second. The actuators can be used in machine tool applications to provide up to 3,400 N-m of torque for fast acceleration and positioning. They are composed of a Harmonic Drive CSG zero-backlash gear and a brushless servomotor. Encoder resolution at the output may be up to 20,971,520 pulses per revolution. They are available with or without a brake and come with several different gear ratios.

Analog-to-Digital Converter Achieves 145dB Dynamic Range
The LTC2380-24 is a 24-bit successive-approximation-register (SAR) analog-to-digital converter (ADC) that operates at low power for applications that require a high dynamic range with low noise in the output. It works well for converting small signals as well. A built-in digital averaging filter averages 1 to 65,536 conversions in real time, and improves the dynamic range from 101 dB at 1.5 Msps to 145 dB at an output data rate of 30.5 sps. Results are read out with a serial clock as low as 2 MHz, easing interfacing to microprocessors and enabling use with slower devices. It achieves true 24-bit noise performance and features high DC accuracy with a maximum integral nonlinearity of ±3.5 ppm while dissipating 28mW from a single 2.5V supply.

Spring-Cage Terminals Accommodate Larger Cable Sizes
Power Turn high-current terminals allow maximum wire sizes from 10 American wire gauge (AWG) to 250 MCM. The terminals have a spring-cage mechanism along with copper clamping connectors to ensure vibration-proof connection. Conductors can be installed with a standard screwdriver and a single-lever movement. For installation locations with limited space, conductors can be directly inserted by closing the lever and using the push-in mechanism. Fully insulated pick-off terminals with double-sided snap-on mechanisms allow voltage tapping of up to four 8-AWG wires per terminal. The terminal unit includes a built-in, double-sided 2.3-mm test socket for standard testing connectors, as well as insulated insertion bridges that may be permanently locked to allow simple voltage distribution.

Hydraulic Gantry Ensures Safe Heavy-Lifting Conditions
The SL400 hydraulic gantry is a high-capacity, bare-cylinder gantry with the electronic and hydraulic systems contained in each leg. The lifting cylinders work in three stages, supporting up to 450 tons at the top of the second stage and reaching heights up to 30 feet at the top of the third stage. It can be remotely operated with an Intellilift wireless control system.
The gantry runs off of a 3-phase power source that can be supplied with a generator. The sturdy base frame can withstand a range of environmental conditions and is equipped with an electronically powered side-shift mechanism. The gantry is tested in overload conditions to ensure accurate nominal lift ratings.
