Inground Transformer 
The Inground Transformer is a buriable unit designed to provide 12 volt power for low voltage luminaires in landscape lighting installations. This transformer is recommended for situations where a Wall Mount unit is either not practical or desirable.
Inground Transformers are available in either 120v 60Hz or 240v 50 Hz and in seven wattages: 20, 40, 50, 80, 100, 150, and 200 watt (each transformer has an IG designation). Models IG100, IG150 and IG200 have individual 50 watt transformers inside the unit with a single output cable, (e.g. IG100 has two 50 watt transformers) instead of one large transformer.
These transformers are “double Insulated safety Isolating” transformers and are suitable for total burial (in locations where this is allowed). The HUNZA In-ground Transformer has a high IPX7 water protection rating. It is critical that all wire connections are made completely waterproof by the use of a HUNZA CJK150 cable joint kit.
For advice on wiring requirements please contact your local HUNZA distributor for a free HUNZA Volt Drop calculator.
Input
120 volt 60Hz or 230–240 volt 50 Hz.
Output
12 volts AC – 50 watt 4.2 amp / 40 watt 3.3 amp / 20 watt 2.0 amp.
Retro™ Pole Transformer 
The Retro Pole 120/240 volt version is available for HUNZA pole mounted fixtures, for example, the 700mm Bollard, Border Lite, Euro Single and Twin Pole Lites, Single and Twin Pole Lites, Twig Lite, Tier Lite and Walkway Lite.
This option is designed for installations where mounting the transformer is a problem and avoids the need to bury a transformer, e.g. where there is a long cable run required and a 120/240 volt power cable needs to be installed.
A situation such as a car park where a ring main has been installed would be ideal for this luminaire.
The electronic transformer is a double insulated safety-isolating transformer and complies to EMC regulations and has a built-in safety shutdown system if it is overloaded.
It will power either 1 x 10 watt, 1 x 20 watt, 2 x 20 watt, 1 x 35 watt, 1 x 50 watt or 2 x 35 watt lamps.
Input
120 volt 60Hz or 230–240 volt 50 Hz.
Output
12 volts AC—75 watt.
LET75 Electronic Transformer
The LET75 (also known as HET75) is a miniature, 75 watt electronic transformer suitable for powering HUNZA luminaires in situations where the transformer is protected from moisture, e.g. inside a waterproof junction box, in a ceiling or in a cavity wall.
The LET75 is available in either 120/12 volt 60Hz or 240/12volt 50/60Hz version, has a built-in safety shutdown system for overload and is dimmable with a leading edge dimmer.
It will power either 1 x 10 watt, 1 x 20 watt, 2 x 20 watt, 1 x 35 watt, 1 x 50 watt or 2 x 35 watt lamps.
Input
120 volt 60Hz or 240 volt 50/60 Hz.
Output
12 volts AC – 75 watt.
Retro™ Wall Transformer 
The Retro Wall Transformer 120/240 volt version is available for HUNZA wall mounted fixtures, for example the Wall Spot, Wall Down Lite, Pillar Lite, Pagoda Lite, Euro Wall Spots and Euro Pillar Lite.
With an electronic transformer built into the luminaire base (canopy), this option is designed for wall installations where mounting a remote transformer is not practical, e.g. in a brick wall where there is no space to recess the transformer or where an existing 120/240 volt light fitting needs to be replaced.
Retro luminaires are a very economical way to overcome potentially expensive installation problems.
With this option the base/canopy increases in depth to 48mm (1 7/8”). All USA Retro wall mount fixtures are supplied with a wide backplate designed to suit a standard 3/0 or 4/0 junction box (this plate must be ordered separately for non-Retro fixtures—/WBAP).
The electronic transformer is 120 or 240/250 volt ac and is encapsulated in silicon. It is rated IP66 against water ingress, has a built-in safety shutdown system for overload and is dimmable with a leading edge dimmer. It will power either 1 x 10 watt, 1 x 20 watt, 2 x 20 watt, 1 x 35 watt, 1 x 50 watt or 2 x 35 watt lamps.
Input
120 volt 60Hz or 230–240 volt 50 Hz.
Output
12 volts AC—75 watt.
Lighting Transformer 
The H Series is an internal (non waterproof) 12 volt lighting transformer designed to operate at the lowest possible temperature.
Due to its low profile the H Series transformer can be fitted through a 63mm (2 1/2”) diameter hole.
Wiring is made much easier by use of a 25 amp (6mm or 1/4” diameter terminal) connector-block, which facilitates quick and easy wire-in and loop-out connections.
For interior use only.
Input
120 volt 60Hz or 230/240 volt 50 Hz.
Output
12 volts AC – 50 watt 4.2 amp / 40 watt 3.3 amp / 20 watt 2.0 amp.
Wall Mount Transformer
The Wall Mount Transformer is an aboveground, waterproof unit designed to provide 12 volt power for HUNZA low voltage luminaires in landscape lighting installations. Wall Mount Series Transformers have a black, glass-reinforced, UV stable nylon case, which provides durability, UV resistance and a low surface temperature.
It is compact and unobtrusive in appearance, blending well into any outdoor setting.
The electrical components are fully encapsulated in the casing for protection against weather and irrigation systems.
The Wall Mount Series is suitable for 120/240 volt 50/60 Hz. operation and is available in 100, 200 and 300 watt versions.
A key feature of this transformer is multi-tap output, providing the choice of either 12, 13 or 14 volt secondary output. This allows much greater flexibility in compensating for voltage drop on long cable runs. For advice on wiring requirements please contact your local HUNZA distributor for a free HUNZA Volt Drop calculator.
The unit has thermal protection for the primary side of the transformer with fuse protection for the secondary. There are 25mm (1”) and 32mm (1 1/4”) conduit entries to allow for different cable requirements.
HUNZA Wall Mount series are “Double Insulated Safety Isolating” transformers.
Input
120 volt 60Hz or 230–240 volt 50 Hz.
Output
12 volts AC.
