Output Load De-rating VS Surrounding Air Temperature 

## **Note** 

1. Power supply components may degrade, or be damaged, when the power supply is continuously used outside the shaded region, refer to the graph shown in Fig. 1. 

2. If the output capacity is not reduced when the surrounding air temperature >60°C, the device will run into Over Temperature Protection. When activated, the output voltage will go into bouncing mode and will recover when the surrounding air temperature is lowered or the load is reduced as far as necessary to keep the device in working condition. 

3. Depending on the surrounding air temperature and output load delivered by the power supply, the device can be very hot!

## **LED Driver** LNE-100W Series / LNEV100W 

## **Functions** 

## Start-up Time 

The time required for the output voltage to reach 90% of its final steady state set value, after the input voltage is applied. 

## Rise Time 

The time required for the output voltage to change from 10% to 90% of its final steady state set value. 

## Hold-up Time 

Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value. 

## **Graph illustrating the Start-up Time, Rise Time, and Hold-up Time** 

## Inrush Current 

Inrush current is the peak, instantaneous, input current measured and, occurs when the input voltage is first applied. For AC input voltages, the maximum peak value of inrush current will occur during the first half cycle of the applied AC voltage. This peak value decreases exponentially during subsequent cycles of AC voltage. 

## Dynamic Response (For CV Operation Only) 

The power supply output voltage will remain within ±5% of its steady state value, when subjected to a dynamic load from 0 to 100% of its rated current.

**TECHNICAL DATASHEET** 

## **LED Driver** LNE-100W Series / LNEV100W 

## Operating Methods of LED Modules-CV and CC Operation 

A typical LED power supply is able to either work in "constant voltage mode (CV) or constant current mode (CC)" to drive the LEDs. Delta’s LNE drivers integrate CV+CC characteristics; so operation in CV mode (with external LED driver), in region `Ⓐ` or CC mode (direct drive, at area `Ⓑ` ). 

In the constant current region, the highest voltage at the output of the driver depends on the configuration of the end systems. 

Should there be any compatibility issues or other questions with these adjustment methods, please contact with Delta. 

## Dimming Operations 

This operation is available for LNE- `☐` V100WD `☐☐` only. 

The Dimming connection diagram for turning the lighting fixture ON/OFF can be configured as below. 

**==> picture [83 x 8] intentionally omitted <==**

Please refer an example of reference configuration as follows. 

1. Built-in 3 in 1 dimming function, IP67 rated.  Output constant current level can be adjusted through output cable by connecting a resistance or 1~10Vdc or 10V PWM signal between DIM+ and DIM-. 

2. The LED lighting fixture can be turned ON/OFF by the switch. 

All parameters are specified at 25°C ambient for all products unless otherwise indicated. **www.DeltaPSU.com (November 2018, Rev. 06)**

**TECHNICAL DATASHEET** 

**LED Driver** LNE-100W Series / LNEV100W 

3. Please DO NOT connect "DIM-" to "V-". 

4. Reference resistance value for output current adjustment (Typical). 

5. 1 ~ 10V dimming function for output current adjustment (Typical). 

6. 10V PWM signal for output current adjustment is also possible. For additional information, please contact your Delta sales representative. 

7. Please note that LNE- `☐` V100WD `☐☐` can't turn the lighting fixture completely off (totally dark) by using any of these dimming adjustment methods. To completely turn off the lighting fixture, the input AC voltage must be removed. See illustration on previous page. 

## External Input Protection Device 

The unit is protected at the L pin, with an internal fuse that cannot be replaced. The power supply has been tested and approved on 20A branch circuits without additional protection device. An external protection device is only required if the supplying branch has an ampacity greater than above. Thus, if an external protective device is necessary, a 20 Ampere C-characteristic circuit breaker can be utilized. 

All parameters are specified at 25°C ambient for all products unless otherwise indicated. **www.DeltaPSU.com (November 2018, Rev. 06)**

**TECHNICAL DATASHEET** 

## **LED Driver** LNE-100W Series / LNEV100W 

## Overload & Overcurrent Protections (Auto-Recovery) 

The power supply’s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current is between 95% and 108% of IO (Max load). Upon such an occurrence, the VO (output voltage) will start to droop. Once the power supply has reached its maximum power limit, the protection will be activated; and, the power supply will operate in “CC mode”. The power supply will recover once the fault condition once the cause of OLP or OCP is removed, and IO is back within the specified range. 

## Overvoltage Protection (Latch Mode) 

The power supply’s overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications defined on Page 6 under “Protections”. Power supply will latch off, and require removal/re-application of input AC voltage in order to restart. 

## **The power supply should be latch.** 

## Over Temperature Protection (Auto-Recovery) 

## Short Circuit Protection (Auto-Recovery) 

The power supply’s output OLP/OCP function also provides protection against short circuits. When a short circuit is applied, the power supply will operate in “CC mode”, as shown in the illustration in the OLP/OCP section on this page. The power supply will return to normal operation after the short circuit is removed. 

As mentioned above, the power supply also has Over Temperature Protection (OTP). In the event of a higher operating temperature at 100% load, the power supply will run into OTP when the operating temperature is beyond what is recommended in the de-rating graph. When activated, the output voltage will go into bouncing mode until the temperature drops to its normal operating temperature as recommended in the de-rating graph. 

## **Others** 

## Delta RoHS Compliant 

## **Restriction of the usage of hazardous substances** 

The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead, mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and electronic equipment. RoHS is the abbreviation for “Restriction of the use of certain hazardous substances in electrical and electronic equipment”. 

This product conforms to this standard. 

## PFC – Norm EN 61000-3-2 

## **Line Current Harmonic content** 

Typically, the input current waveform is not sinusoidal due to the periodical peak charging of the input capacitor. In industrial environment, complying with EN 61000-3-2 is only necessary under special conditions. Complying to this standard can have some technical drawbacks, such as lower efficiency as well as some commercial aspects such as higher purchasing costs. Frequently, the user does not profit from fulfilling this standard, therefore, it is important to know whether it is mandatory to meet this standard for a specific application.
