Diagrams and Characteristics

Block Diagram

The block diagram illustrates the internal components and signal flow of the FDL-65 series LED driver. It includes an EMI filter and rectifiers for input processing, followed by power switching and a PWM & PFC control unit. The output stage consists of rectifiers and a filter, with a detection circuit feeding back to the control unit. Protection circuits such as Over Voltage Protection (OVP), Over Temperature Protection (OTP), and Over Load Protection (OLP) are integrated. The unit also features Case Ground for EMC compliance.

Driving Methods of LED Module

This series operates in constant current mode to directly drive LEDs. The graph shows the 'Constant Current area' and 'Hiccup Protection' region. In the constant current region, the output voltage is dependent on the configuration of the end system.

Output Load vs Temperature

Two graphs illustrate the output load capacity relative to temperature. The first graph shows Load (%) versus Ambient Temperature (Ta in °C), indicating the operating range from -40°C to +70°C. The second graph shows Load (%) versus Case Temperature (Tcase in °C), with an operating range from -40°C to +90°C.

Static Characteristic

This graph displays the relationship between Input Voltage (V) and Load (%) at 60Hz. The FDL-65 series operates within an input voltage range of approximately 180V to 295V.

Power Factor (PF) Characteristic

The power factor is shown as a function of Load (%) at a case temperature of 80°C. Separate curves are provided for 230V and 277V input voltages, demonstrating a high power factor across the load range.

Total Harmonic Distortion (THD)

This graph illustrates the Total Harmonic Distortion (THD) as a function of Load (%) for the 1800mA model at a case temperature of 80°C. Curves are shown for 230VAC and 277VAC input, indicating THD is generally below 20% for loads above 60% (230VAC) or 75% (277VAC).

Efficiency vs Load

The efficiency of the FDL-65 series is presented as a function of Load (%) at a case temperature of 80°C. Curves for 230V and 277V input show that the efficiency reaches up to 90% in field applications.

Mechanical Specification

The mechanical specifications include the overall dimensions: 151mm (Length) x 53mm (Width) x 31.5mm (Height). Input connections are AC/N (Blue) and AC/L (Brown) using H05RN 1.0mm²*2C cables. Output connections are -V (Blue) and +V (Brown) also using H05RN 1.0mm²*2C cables. Mounting holes are indicated. The note specifies connecting the case to FG (Frame Ground) for complete EMC deliverance. The product is IP65 rated.
