www.efore.com Page 1 KPD_Ozone 150W_Rev04 September 2016

DESCRIPTION Ozone 150W is a programmable LED Driver that combines smart technology and high flexibility features.

A single channel, constant current LED ballast, Ozone is designed for directly powering up LEDs in high power indoor and outdoor lighting fixtures, such as street and tunnel lighting, parking lot and wide area lighting, as well as in industrial and high bay lighting applications.

Designed in a super compact package 195 x 60 x 35mm (7.68” x 2.36” x 1.37”), the Series includes only four different models that cover applications from 50V to 295V, with currents from 200mA to 1500mA.

The intelligent core of the driver permits to program the output current in 50mA steps inside the range of each model, which makes the Ozone extremely flexible and suitable for different kind of applications.

By converting energy at 93% typical efficiency, the Ozone Series makes easier the thermal management in space constrained systems, offering high reliability in environmentally friend solutions.

DALI/PWM interface makes the driver configurable through the standard control protocols.

With the optional Ozone Programming Tools and the free Ozone Toolset Software, users can implement advanced functions, such as the Adjustable Dimming, Constant Light and Diagnostic ones, which eliminate the need for any additional electronics inside the fixture except the LEDs themselves.

EFFICIENCY AND PFC PERFORMANCE Ozone 150W LED Driver shows very good efficiency and power factor performance even when operating at low loads. For each model the typical efficiency value is 93% at 230VAC, while the PF is >0.9 from 100% max load at 277VAC, 50% max load at 240VAC, 50% max load at 277VAC. Following are the characteristic plots for the four Ozone LED driver models, referring to the maximum output voltage operating condition.

RSOZ150-105-DALI RSOZ150-120-DALI




UNDER-VOLTAGE DIMMING OPERATION Ozone 150W LED driver is able to operate under the minimum value of the output voltage range in order to allow dimming functions through an analog signal (0-10V, 1-10V or variable resistor) or a DALI/PWM signal. It is therefore possible to reduce the output current starting from a full load condition located near the bottom value of the output voltage spec (Vout min), without any problem. The dimming profile is different for each Ozone model and it is reported in the following plots, where the yellow area represents all the possible programmable working points, while the orange area is reached only under dimming conditions.

The under voltage areas, below the minimum output voltage value, can be reached only under dimming operations; if the driver enters the under voltage region when operating at nominal current it will automatically shut down. In particular at nominal current, the driver shuts down when the voltage drop on LEDs is lower than the minimum allowed one minus 2V of margin. Periodically the system checks if the underload condition still exists, recovering the normal operation if it’s removed. After 4 attempts of restart, the driver remains in protection mode (no output current) until it is powered off and on again. The final application should be designed in order to operate always within these characteristics.




INTELLIGENT COLD START FUNCTION In order to fully cover all the available output voltage range, Ozone LED driver introduces an intelligent control of the LED load voltage at start up. For each settable current, the driver temporary accepts and controls an overload voltage higher than the maximum specified one (while the LEDs are cold), permitting therefore to operate very close to the upper limit of the range when the LEDs heat up. If the output power is higher than 150W and lower than 160W ( for RSOZ150-180-DALI and RSOZ150-300-DALI) or higher than 120W and lower than 130W (for RSOZ150-120-DALI) ,the driver will reduce the output current (in about 1s) until the output power goes under 150W ( for RSOZ150-180-DALI and RSOZ150-300-DALI) and 120W (for RSOZ150-120-DALI). When this protection is active, and at least 60s after the last current decrease, the driver will check if the output power is lower than 150W (120W for RSOZ150-120-DALI): in this case it will increase the current (1mA every 1s) until the output power is lower than 150W (120W RSOZ150-120-DALI) and the current is lower than the nominal one. If the output power is higher than 160W (for RSOZ150-180-DALI, RSOZ150-300-DALI) or 130W (for RSOZ150-120-DALI), the driver shuts down. After 5s it checks if this condition still exists, trying to restart and recovering the normal operation. If the overload condition is still present, after 4 attempts of restart, the driver remains in protection mode (no output current) until it is powered OFF and on again. The No load condition is managed in the same way. Please note that the RSOZ150-105-DALI doesn’t present the intelligent cold start function. Referring to Ozone RSOZ0150-300-DALI the following plot explains the Intelligent Cold Start Function and the different working regions.

OUTPUT RIPPLE CURRENT CHARACTERISTICS The driver’s digital control of the output current permits to maintain a very low ripple current value on the LED string for all over the different voltage/current working points. The ripple current value is usually higher when operating at full power towards the upper limit of the output voltage range, while it decreases significantly (under 10% of the set current) for working voltages located near the bottom value of the range. Following are reported the ripple current measurements and plots for each Ozone model.
