Failsafe and Modulating Electric Actuators from Stock
This new concept was a huge success and as more competitors release products with similar facilities, in 2017 J+J raise the bar again. The target was to reduce the current ‘high’ and ‘low’ voltage versions into one model that covered both.
After years of head-scratching, and with a patent pending to protect the concept, Jordi Chaves (one of the ‘J’s’ in ‘J+J’) finally solved the problem and the new ‘S’ Type released in the last quarter of 2016 boasts single multi-voltage capability with auto-sensing of any supply voltage between 24 and 240VAC or DC. Now, with only a single model to cover what formerly required two to cover the range, the J3C-S Series from J+J gives stockists a smart actuator with the flexibility to make the ROI on stock-holding interesting once again.
The BSR plug and play function conversion kit quickly and easily creates fail-safe functionality using an industrial rechargeable battery and PCB containing a trickle charging system and switch to draw battery power when external power fails. Installed inside the original on-off actuator’s housing to maintain the same size envelope (many competitors still add a separate housing for the battery – as J+J did prior to 2007), the BSR only sees a change in connectivity to the new ‘S’ Series control PCB.
However, function conversion from on-off to modulating sees a significant change in the new ‘S’ Type, where the former mechanically driven potentiometer shaft feedback system is superseded by state of the art digital magnetic position sensing. In a new, even more user-friendly auto-calibrating plug and play kit, the DPS system significantly upgrades the performance of the J+J smart actuator’s proportional control. To indicate this change, the now multi-colour LED status light is blue for proportional control.
In most cases, the plug and play BSR and/or DPS kits are installed by the stockist and dry bench function tested before shipping to the installer or user and with the now super-flexibility of a single multi-voltage actuator supported by the plug and play function conversion kits, the J+J ‘S’ Type offers delivery from stock of failsafe, modulating – or with both kits installed, failsafe modulating smart electric actuators.
As the kits are so user friendly, and quick and easy to install, they can be quickly and easily retro-fitted on site should the function in the process system in which they are installed, change.
