HiPASS Series VFD Distributor

Hitachi Introduces New HiVAC Inverters & HiPass Bypass Packages for Optimum Energy Savings

Hitachi America, Ltd., Power and Industrial Division, today announced its new HiVAC Series of inverters. The HiVAC inverters are ideal for a wide variety of variable torque applications, including fans, cooling towers and pumps. HiVAC features include: PID (Proportional-Integral-Derivative) control and automatic energy savings, anti-wind-milling, loss of reference signal, intelligent terminal systems, three (3) programmable output relays, and RS485 communications.

HiVAC with SC-OPE3H enhanced HVAC LCD keypad will have embedded Building Automation System protocols such as Johnson Controls Metasys N2, Siemens APOGEE FLN, MODBUS-RTU, BACNET. An optional LonWorks interface card also is available. The LCD keypad is also equipped with Hand/Off/Auto, Quick Menu, Read/Write function.

The HiPASS bypass package is designed for crucial applications so that no system downtime can occur and the customer's system can remain in operation. In HVAC applications, this allows heating or cooling to be maintained at all times. With use of standard PID control, desired temperature can be accurately maintained.

The HiPASS Package has been designed for ease of drive commissioning and system setup. The compact and space saving NEMA 1 Side by Side Wall mountable enclosure design allows for use of minimum wall space. All HiPASS Package internal components are easily accessible due to thoughtful design practices. The HiPASS user-friendly customer terminal strip allows access to the HiVAC drive's intelligent inputs, analog inputs and BAS (Building Automation Systems) connections.

Hitachi SJ700B Series Industrial AC VFD Distributors

Hitachi Introduces the SJ700B Series of Advanced 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 possible as well through an optional board. The SJ700B also has a number of built-in features that make the commissioning process quick and the operation of the control trouble-free.

Another notable upgrade in the SJ700B is the higher operating temperature range of -10°C to 45°C . The SJ700B is loaded with additional application integration features such as Hitachi's EzSQ (Easy Sequence) built-in programming function, which provides the functionality of a PLC built into the inverter. Due to this internal capability, in many cases, the need for a separate PLC can be eliminated or the I/O reduced. Programs for various applications such as irrigation pump control or repeatable motion profiles can be developed on a PC and then downloaded to the inverter with the easy-to-use EzSQ software provided at no charge.

The other new helpful features Hitachi has added to the SJ700B include the patented micro-surge voltage suppression to protect the motor winding insulation, advanced trip avoidance functions, configurable sink/source logic on digital inputs, PID, built-in dynamic braking circuit in models up to 40 HP (30 kW,) and built-in EMC filters in all models. The SJ700B also incorporates features customers have come to expect from Hitachi Variable Frequency Drives. Some of the anticipated features include built-in RS485 Modbus/RTU communication. The SJ700B can be configured via the front-mounted keypad or using Hitachi's ProDriveNext PC-based software. A truly globally accepted product, the SJ700B is CE, UL, c-Tick-certified and RoHS-compliant.

Hitachi NE-S1 Series Economical VFD with Simple Operation Distributors

NE-S1 is the Optimal Control for Simple Speed Control Solutions

Hitachi America, Ltd., Industrial Components & Equipment Division, today announced the launch of its next generation inverter, the NE-S1. Hitachi America, Ltd. is now pleased to offer these economical and simple to use inverters in the popular HP range of 1/2 to 3 hp. The NE-S1 is designed to be ultra-compact to meet the needs of both OEMs and System Integrators.

The NE-S1 variable frequency drive offers the end user and integrator the ability to use the control as is out of the box, with popular preconfigured and simple defaults settings. In addition, a wide variety of options are available to configure the control for a specific application. These powerful pre-configured inverters allow for the use of remote mounted speed potentiometers, contacts or switches, and preset speed selections without any parameter changes thus saving time during the installation and integration process.

A wide variety of keypad options are also available to make the NE-S1 inverter a full keypad configurable unit, complete with a built-in speed potentiometer. High volume applications will benefit from the use of our downloadable ProDriveNext software to configure the inverter for further flexibility. The NE-S1 allows for the end user to choose the level of customization required that best fits their application, offering the best overall installed value.
