Thermal Details and Lifetime
2.1 Expected Lifetime
The LED drivers are designed for a lifetime stated above under reference conditions and with a failure probability of less than 10%. Lifetime declarations are informative and represent no warranty claim.
The relation of tc (casing temperature) to ta (ambient temperature) depends on the luminaire design. If the measured tc temperature is approximately 5 K below tc max., ta temperature should be checked and critical components measured. Detailed information is available upon request.
| Ambient temperature ta | Casing temperature tc | Lifetime |
|---|---|---|
| 40 °C | 75 °C | 50,000 h |
| 50 °C | 85 °C | 30,000 h |
Installation and Wiring
3.1 Circuit Diagram
Circuit diagram illustrating the connection of the TRIDONIC LC 35W 800mA fixC SR SNC2 LED driver, showing input (220-240 V, 50/60 Hz, L, N) and output (LED+, LED-) connections.
3.2 Wiring Type and Cross Section
For wiring, use stranded wire with ferrules or solid wire from 0.5-1.5 mm². Strip 8.5-9.5 mm of insulation from the cables to ensure perfect operation of the push-wire terminals. Use one wire per terminal connector. The maximum torque at the clamping screw (M3) is 0.3 Nm.
Diagram showing recommended wire specifications: wire cross-section 0.5 - 1.5 mm², strip length 8.5 - 9.5 mm, and cable diameter range (max. Ø = 6.6 mm, min. Ø = 3.3 mm).
3.3 Release of the Wiring
Press down the "push button" and remove the cable from the front.
3.4 Fixing Conditions
Mounting surface should be dry, acid-free, oil-free, and fat-free. Do not exceed the maximum ambient temperature (ta) stated on the device. Minimum distances shown are recommendations and depend on the luminaire design. Not suitable for fixing in a corner.
Diagram showing recommended minimum distances: >100 mm from luminaire casing, >20 mm clearance around the driver. Indicates ambient temperature (ta) and casing temperature (tc) relationship.
3.5 Wiring Guidelines
- Keep all connections as short as possible for good EMI behaviour.
- Keep mains leads separate from LED driver and other leads (ideally 5-10 cm distance).
- Maximum length of output wires is 2 m.
- Run secondary wires (LED module) in parallel to comply with EMC regulations.
- Secondary switching is not permitted.
- Incorrect wiring can damage LED modules.
- Protect wiring against short circuits to earth (e.g., sharp metal parts, cable clips, louvers) to prevent driver damage.
3.6 Replace LED Module
- Turn off mains power.
- Remove the LED module.
- Wait for 20 seconds.
- Connect the new LED module.
Hot plugging or secondary switching of LEDs is not permitted and can cause very high current to the LEDs.
3.7 Installation Instructions
The LED module and all wiring contact points must be sufficiently insulated against 3 kV surge voltage. Air and creepage distances must be maintained.
3.8 Mounting of Device
Maximum torque for fixing: 0.5 Nm/M4.
Electrical Values
4.1 Diagrams
4.1.1 Efficiency vs Load
Graph showing the relationship between efficiency (in %) and load (in %). The efficiency is approximately 90% at full load and varies slightly with load percentage.
4.1.2 Power Factor vs Load
Graph showing the relationship between power factor and load (in %). The power factor is consistently high, around 0.95, across the load range.
4.1.3 Input Power vs Load
Graph showing the relationship between input power (in W) and load (in %). Input power increases linearly with load, from approximately 25 W at 65% load to 40 W at 100% load.
4.1.4 Input Current vs Load
Graph showing the relationship between input current (in mA) and load (in %). Input current increases linearly with load, from approximately 130 mA at 65% load to 190 mA at 100% load.
4.1.5 THD vs Load
Graph showing the Total Harmonic Distortion (THD) of the input current (in %) versus load (in %). THD is highest at lower loads (around 13% at 65% load) and decreases as the load increases, reaching about 8% at 100% load.
Maximum Loading of Automatic Circuit Breakers
This table shows the maximum loading of automatic circuit breakers in relation to inrush current for different types (C10, C13, C16, C20, B10, B13, B16, B20) and installation wire cross-sections (1.5 mm², 2.5 mm²). These are maximum values calculated from continuous current at full load, with no limitation due to inrush current.
| Automatic circuit breaker type | Installation 1.5 mm² | Installation 2.5 mm² | ||||||
|---|---|---|---|---|---|---|---|---|
| C10 | C13 | C16 | C20 | B10 | B13 | B16 | B20 | |

Inrush Current
Imax: 10 A, Time: 100 µs
Harmonic Distortion in the Mains Supply
Harmonic distortion in the mains supply (at 230 V / 50 Hz and full load) for the LC 35/800/43 fixC SR SNC2 is detailed for different harmonic orders (3, 5, 7, 9, 11). Values are generally low, e.g., THD < 15% for 3rd and 5th harmonics, and < 3% for 11th harmonic. Harmonics < 5 mA or < 0.6% (whichever is greater) of the input current are not considered for THD calculation, according to EN 6100-3-2.
Functions
5.1 Short-circuit Behaviour
In case of a short circuit on the secondary side (LED), the LED driver switches into hic-cup mode. It recovers automatically after the fault is eliminated.
5.2 No-load Operation
The LED driver operates in burst working mode, providing a constant output voltage regulation. This allows safe operation even if an LED string opens due to failure.
5.3 Overload Protection
If the maximum load is exceeded, the LED driver will protect itself, potentially causing LEDs to flicker. Nominal operation is restored automatically after the overload is removed.
Miscellaneous
6.1 Insulation and Electric Strength Testing of Luminaires
Electronic devices can be damaged by high voltage. During routine luminaire testing in production, consider the following:
According to IEC 60598-1 Annex Q or ENEC 303-Annex A, luminaires should undergo an insulation test with 500 V DC for 1 second between interconnected phase/neutral terminals and the earth terminal. The insulation resistance must be at least 2 MΩ.
An alternative test of electrical strength with 1500 V AC (or 1.414 x 1500 V DC) is described in IEC 60598-1 Annex Q. To avoid damage to electronic devices, this test must not be conducted.
6.2 Conditions of Use and Storage
Humidity: 5% up to max. 85%, non-condensed (max. 56 days/year at 85%).
Storage temperature: -40 °C up to max. +80 °C.
Devices must be within the specified ambient temperature range (ta) before operation.
6.3 Maximum Number of Switching Cycles
All LED drivers are tested with 50,000 switching cycles.
