Inventronics can now supply two-phase fed IP66/67 drivers in smaller power ratings. This EMS family has a wide input voltage range of 249-528 Vac.
Two-phase feeding is sometimes necessary because a neutral is missing. But in other cases it may make sense because it increases efficiency. This allows some degree of omission of cooling and thus allows more compact construction.
ESM-075SxxxDx, the newest and also smallest model in 75W, like the larger versions, has programmable options with an output of 700-2100mA. These compact drivers offer isolated dimming options such as 1-10V, 10V PWM, (>75W also DALI) and timers, as well as lumen compensation for uniform light quality.
These EMS drivers have surge protection up to 10kV (CM), lifetime up to 102,000 hours at Tc=70°C and efficiency up to 96%.
The ESM family includes several programmable models with powers ranging from 75W to 1200W and is specifically designed for demanding applications such as high bays, greenhouses, tunnel and street lighting.
