Upgraded 6 Amp Relay satisfies need for high power in miniature format
Hongfa ’ s HF18FH , part of Hongfa Plug in relay range , is a 6 Amp 4 Pole miniature high power relay operating from an AC or DC supplies . Hongfa have improved the HF18FH from the industry standard 5 Amp 250VAC / 30VDC to an improved 6 Amp 250VAC / 30VDC . This relay enables manufacturers and end users to use a small , high-power relay where a greater switching current is needed or preferred .
Alongside the improved 6 Amp rated contacts , the relay boasts built in LED , Lockable Test Button and Mechanical Flag Indicator .
Hongfa have also taken the opportunity to change the colour of the relay case , from a translucent smoked brown colour to a more aesthetically pleasing clear transparent case . This enables the operator to clearly see the Relays switching contact and the internal LED and Mechanical flag indicator .
The forementioned LED has also been improved , Hongfa have moved away from a polarity sensitive LED to an LED which will operate on both the positive and negative terminals . Previously the relay needed to be wired with the correct terminal arrangement for the LED to operate . With the new relay either terminal can be used allowing greater flexibility to the installer .
The LED along with the Mechanical test button is colour coded , Red LED with Orange Test Button for AC Coils and a Green LED with Blue Test Button for DC Coils .
Aimed at OEMs , CEMs , panel builders and equipment manufacturers , the HF18HF is suitable for a diverse range of applications such as control panels , pumping applications , lift manufacturers , stair lifts and vending machines .
The relay measures just 37.0 x 21.5 x 28mm , and three versions of the relay are available : a 7A 2 Pole DPDT , a 7A 3 Pole 3PDT , and a 6A 4 Pole
