Hitachi America, Ltd., Industrial Components & Equipment Division, today announced the new WJ200 series of inverters. This new model advances the benchmark for performance and functionality in micro-size AC drives. The WJ200 is a sensorless vector (SLV) drive capable of 200% or greater torque across the speed range.  Speed regulation at low speed is dramatically improved – fluctuation is half that of previous models. Improved trip avoidance measures have been incorporated for unsurpassed system reliability and availability. The WJ200 offers PLC-like functionality by means of the integrated Easy Sequence (EzSQ) programming function. Programs up to 1024 lines can be created on a PC using this structured language tool, and can then be transferred to the WJ200. In this way, very sophisticated control schemes can be created without the use of external controllers. Simple position control applications are also possible with the WJ200 utilizing the integ...

The new VACON X5 HazLo© AC Drive's unique design provides your application solution in a compact, cost effective patent designed unit. This drive has been certified for Division 2 hazardous locations, suitable for petroleum refineries, gasoline storage and dispensing areas as well as utility gas plants. In a class of its own, the VACON X5 HazLo drive has a robust design with safety yellow colored metal covers to protect against bumps and misuse.  Because there is not an additional box needed to place the drive in, cooling concerns are not an issue. This allows for even greater mounting flexibility without having to spend more money in installation costs. The VACON X5 HazLo is availabe in frame size T3 and T4 for applications ranging from 40 to 100 HP. Continuing to be the toughest AC drives on the planet, VA...

Designed to set new benchmarks in ease of use for simple machine control, the ACS250 is designed to meet the production and performance needs of system integrators, original equipment manufacturers (OEMs) and panel builders, as well as the requirements of end users in a broad range of applications - from augers, mixers, pumps, and fans, to conveyors. The drive offers two degrees of environmental protection, starting with the standard IP20 panelmounted chassis. For more demanding environmental conditions, such wash-down applications that require on-machine mounting, the IP66/UL Type 4x drive is the perfect solution. With its feed-thru wiring, the IP20 chassis drive easily can replace motor starters, to improve overall energy efficiency, reduce mechanical stresses and enhance the process control of many ...

Hitachi America, Ltd., Industrial Components and Equipment Division, today announced the introduction of the SJ700B Series of Industrial AC Variable Frequency Drives, with full availability in late October. The SJ700B significantly expands on the performance, capabilities and functions of its predecessor, the L700. To reassert its technological leadership and ensure unmatched performance, Hitachi has broadened the applicability of this new series by incorporating and upgrading many of the original flagship SJ700 features, such as the industry-leading Sensorless Vector (SLV) control algorithm. This algorithm enables the SJ700B to develop 120% of full torque capabilities at 0 Hz in Hitachi's exclusive "0 Hz Domain" sensorless vector control mode, as well as 150% torque at 0.5 Hz in ...

Pulse transformer technology for isolating I/O signals offers significant advantages over optical isolation and electromechanical relays. Most notably, pulse transformer I/O modules provide higher transient immunity and high input-to-output isolation. The high transient immunity means the Weidmuller - Delcon I/O modules are ideal for I/O applications where electrical noise is a problem. No additional suppression components are needed even when used with long unshielded signal cables, inductive loads or ‘noisy’ power lines. The limitations of optocoupler based solid-state relays disappear when pulse transformer I/O modules are used. For instance, the standard AC output module SLO 24TR has near zero leakage current; requires no minimum load; can be used with any power factor 0 to 1; is rated for both general use and inductive loads at 3A; and is immune to both load line and signal line spikes. Features: • virtually no off-state leakage currents • high current and high voltage D...

No challenge is too great or single application too small. From industrial plants to OEMs to municipal water and wastewater treatment facilities, Lenze pump solutions are hard at work. Versatile and robust, our industrial drives and controls are cost-effective and low-maintenance. Our focus is on variable speed flow and pressure control so whatever your specific application requires, Lenze has the drives and controls to match form, fit and function. Centrifugal pumps Centrifugal, or Variable Torque pumps, are used in a wide range of commercial, industrial and municipal applications. Throttling valves are a common flow control method. Compared to a throttling valve, the lower power requirements of the SMVector VFD provide a greater energy savings. Operating at 75% flow reduces power demand by over 50% with an SMVector Drive, while a throttling valve requires about 90%. Typical applications •Chilled and Hot Water Pumps •Condenser Water Pumps •Booster Pumps •Potable Water Pum...

When dealing with the core elements of a system with a large risk potential, it is especially critical to have the best system solution in place. Our SIL relays reliably switch off your systems in critical situations – and they have all been accredited. Let's connect. Whether for a burner control system, secure emergency shut down or, for example, for pump controllers – our safety relay guarantees safe conditions and encompasses highly superior and significant features. Their integration into distributed control systems (DCSs) is even better, with an input filter which makes the SIL circuit immune to the test impulse which is typically used by a DCS. You will also benefit from simple maintenance: the fuses are accessible from the outside and can easily be changed. You can see the status of the safety a...
