Protect Your Connection with Isolated Ultra-Small and Strong USB to Serial

Brainboxes releases the US-159 small profile USB to Serial device with isolation. We have given our customers the ‘just works’ reliable USB to Serial connection they have come to expect from Brainboxes but with the added security of isolation, perfect for demanding industrial environments. The US-159 gives an RS-232 serial connection on one end with a high retention USB connection of the other. All connections are electronically isolated from one another in our smallest toughest case yet. The US-159 case is in our ultra-small form factor, and can cope with industrial temperatures, is IP50 rated and has a high retention USB connection. Really tough, can’t be snapped or crushed and is well sealed limiting ingress from dirt and moisture and works from -40°C to +80°C (-40°F to +176°F). Isolation prevents electrical damage to your expensive equipment. The US-159 has 2kV of isolation protecting from high voltage spikes, and ground potential difference. With all the different equipmen...

Hitachi Introduces the SJ700D Series of Dual Rated Advanced Industrial AC Variable Frequency Drives for Both Constant and Variable Torque Applications

Hitachi America, Ltd., Industrial Components and Equipment Division, today announced the introduction of the SJ700D Series of Industrial AC Variable Frequency Drives,  with  full  availability  in  February.  The  SJ700D  significantly  expands  on  the  performance, capabilities and functions of both its predecessors, the SJ700 and the SJ700B. Hitachi has once again broadened the applicability of this new series by incorporating and upgrading many of the original flagship SJ700 features and incorporating them into a new, more versatile variable frequency drive package. Therefore, the new SJ700D drives are ideal for a complete wide range of applications beyond variable torque applications such as fans and pumps, or constant torque applications such as material handling or extrusion equipment. The new SJ700D also has a number of built-in features that make the commissioning process quick and easy, such as single parameter ch...

Hitachi Introduces High Performance AC Drive Model

Hitachi America, Ltd., Industrial Components & Equipment Division, today announced the new SJ700-2200HFU2 model inverter, with a 440 A output current capability. This new model fills in the gap at 300-350 hp in the SJ700 series, which now completely covers the range from ½ to 600 hp. The SJ700 significantly expands on the performance, capabilities and functions of its predecessor, the SJ300. Hitachi reasserts its technological leadership with an improved vector control algorithm and auto-tuning function that enables the open-loop SJ700 (SLV) to develop more than 200% starting torque at 0.3 Hz. Using Hitachi’s unique “0 Hz Domain” open-loop control mode, the SJ700 can develop 150% torque near 0 Hz, ideal for vertical lift applications. In closed-loop mode with encoder feedback, the SJ700 performance is unmatched, delivering in excess of 100% torque at 0 Hz. Another major new element in the SJ700 is Hitachi’s EzSQ (Easy Sequence) built-in programming function. It’s like having ...

Hitachi Introduces New Advanced AC Micro Drives

Hitachi America, Ltd., Industrial Components & Equipment Division, today announced two new 100 V Class models in the innovative WJ200 series of inverters. The new models are rated at ½ hp and 1 hp, 100-120 VAC, single-phase input, and 200-240 VAC, 3-phase output. The WJ200 series sets a new benchmark for performance, flexibility 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 is distinguished by its integrated PLC-like functionality. With its powerful Easy Sequence (EzSQ) logic controller function, programs up to 1024 lines can be created on a PC using a structured language editing tool. These programs can then be transferred to the WJ200 to control its operation...

Hitachi Introduces the SJ700B Series of Advanced Industrial AC Variable Frequency Drives for Fans, Pumps, Conveyors and More

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 sensorless vector operation mode in most models, which is ideal for a wide range of applications beyond just fans and pumps. Additionally, operation in the closed-loop full vector control mode is now possi...
