Technical Diagrams and Performance

Block Diagram

The block diagram illustrates the internal architecture of the XLG-200 series driver. It shows the signal flow starting from AC input (AC/L, AC/N, FG [ground symbol]), passing through an EMI filter and rectifiers, followed by a PFC circuit for power factor correction. The core of the driver is the power switching stage controlled by PWM control, with protection circuits like Over Load Protection (OLP), Over Temperature Protection (OTP), Over Current Protection (OCP), and Over Voltage Protection (OVP) integrated for safety and reliability. The output stage includes rectifiers and filters, with dimming control (DIM+, DIM-) available for the AB type.

I-V Operating Area

The I-V operating area graphs define the valid output voltage and current ranges for different models. For example, the XLG-200-L series typically operates with a constant current range from 700mA to 1050mA and output voltages up to 285V, while the XLG-200-H series handles higher currents up to 5550mA with lower output voltages down to 27V. These graphs indicate the regions where the driver operates in constant voltage mode (e.g., area A) and constant current mode (e.g., area B), with a hiccup protection mode (e.g., area C) for fault conditions.

Dimming Operation (3-in-1)

The XLG-200 series (AB type) supports 3-in-1 dimming, allowing adjustment of the output constant current using one of three methods:

• 0-10VDC: Applying a voltage between 0V and 10V to the DIM+ and DIM- terminals adjusts the output current proportionally.
• 10V PWM Signal: A PWM signal with a frequency range of 100Hz to 3KHz applied to DIM+ and DIM- controls the output current based on its duty cycle.
• Resistance: Connecting a variable resistance across DIM+ and DIM- also adjusts the output current.

Note: The minimum dimming level is approximately 8% output current. The output current can drop to 0% at minimum dimming inputs (0V, 0kΩ, or 0% PWM duty cycle). It is crucial not to connect DIM- to Vo-.

Performance Characteristics

Output Load vs. Temperature: These graphs illustrate the maximum allowable load percentage based on ambient and case temperatures for different input voltages (110VAC, 230VAC). For instance, at 230VAC input, the maximum case temperature (Tcase) for full load operation is typically around 75°C, with derating required at higher temperatures or lower input voltages.

Static Characteristic (Input Voltage vs. Load): This graph shows how the output load (as a percentage of rated current) is maintained across a wide range of input voltages (100-305V AC).

Power Factor (PF) Characteristic: The PF remains high (typically above 0.95) across various load levels for different input voltages, indicating efficient power utilization.

Total Harmonic Distortion (THD): THD is generally low, especially at higher load levels and typical input voltages, meeting relevant standards.

Efficiency vs. Load: The XLG-200 series achieves high efficiency, often exceeding 90% and reaching up to 94% at optimal load conditions across different input voltages.

Lifetime

The lifetime of the LED driver is significantly influenced by its operating case temperature (Tcase). The provided graph shows that the expected lifetime (in thousands of hours, Kh) remains high (around 100 Kh) up to a Tcase of approximately 75°C. Beyond this point, the lifetime decreases as the Tcase increases.

Mechanical Specifications

The XLG-200 series is available in different types (Blank, A, AB) with consistent dimensions:

• Dimensions: 199mm (Length) x 63mm (Width) x 35.5mm (Height)
• Weight: 0.85 Kg
• Input/Output Wiring: Standard SJOW/H05RN-F cables are used for AC input and DC output. Specific cable types and gauges are detailed for different models (e.g., 17AWG for AC, 14AWG or 17AWG for DC output depending on voltage).
• Mounting: The metal case allows for mounting in various orientations. Mounting holes are indicated in the diagrams.
