Description

The SSM-1K0SxxxMGR series is a 1000W, constant-current, programmable and IP66-rated LED driver that operates from 249-528Vac input with excellent power factor. Created for many lighting applications including high mast, sports, UV-LED, aquaculture horticulture, etc. It provides a rotary switch, RJ12 connector and dim-to-off functionality. The dimming control supports 0-10V dimming as well as two-way communication via Digital Dimming, a UART-based communication protocol. The high efficiency of these drivers and compact metal case enables them to run cooler, significantly improving reliability and extending product life. To ensure trouble-free operation, protection is provided against input surge, input under voltage, input over-voltage, output over-voltage, short circuit, and over-temperature.

Hot-plugging Protection
This feature protects LEDs when connecting to a driver that is already powered on. This is disabled by default and can be enabled through the Inventronics Programming Software.

• The LED threshold voltage (Vth) is the minimum voltage required for current to flow through the LED load. After this threshold is met, the LED forward voltage (Vf) increases as the current increases.
• Set Vth close to, but higher than the actual LED threshold voltage for optimized performance. The greater the difference between the Vth setting and the actual LED threshold voltage, the higher the overshoot current will be. The Vth setting must be lower than Vf.
• Please test, program, and tune this feature for each LED load design.

Hot-plugging Protection (Continued)

Parallel LED Protection
This feature helps protect parallel LEDs from a high, overcurrent condition by limiting the voltage. This is disabled by default and can be enabled through the Inventronics Programming Software.

• Set V_overload close to, but higher than the maximum forward voltage for optimized performance. The greater the difference between the V_overload setting and the maximum forward voltage, the higher the overload stress will be. The V_overload setting must be higher than Vf.
• Please test, program, and tune this feature for each LED load design.

Rotary Switch and RJ12 Connector
The output current can be set as 0, 40%, 60%, 80%, 100% level by the rotary switch and the output current can be dimmed by the dimming wire in the RJ12 connector when the rotary switch is at ‘EXT’ position. The default mode is in ‘EXT’

Dimming

0-10V Dimming
The recommended implementation of the dimming control is provided below.

Notes

1. Do NOT connect Dim− to the output V− or V+, otherwise the driver will not work properly.
2. The dimmer can also be replaced by an active 0-10V voltage source signal or passive components like a zener.
3. When 0-10V negative logic dimming mode and Dim+ is open, the driver will dim to off and be on standby.

PWM Dimming
The recommended implementation of the dimming control is provided below.

Notes

1. Do NOT connect Dim− to the output V− or V+, otherwise the driver will not work properly.
2. When PWM negative logic dimming mode and Dim+ is open, the driver will dim to off and be on standby.

Resistor Dimming
The recommended implementation of the dimming control is provided below.

Notes

1. Do NOT connect Dim− to the output V− or V+, otherwise the driver will not work properly.
2. When resistor negative logic dimming mode and Dim+ is open, the driver will dim to off and be on standby.

Adjustable Dimming Curve
The 0-10V dimming curve can be set as the corresponding dimming voltage by the Inventronics Multi Programmer. Take the positive logic dimming as an example, the recommended implementation of the dimming control is provided below.

Notes

1. Do NOT connect Dim− to the output V− or V+, otherwise the driver will not work properly.
2. The dimmer can also be replaced by an active 0-10V voltage source signal or passive components like a zener.
3. When the dimming voltage X point is set to be smaller than the Y point, the dimming curve is positive logic; conversely, when the X point is set to be bigger than the Y point, the dimming curve is negative logic.
4. For best dimming accuracy, the difference between the X point and Y point is advised more than 4V.
5. Dimming off voltage adjustable.

Time Dimming
Time dimming control includes 3 kinds of modes, they are Self Adapting- Midnight, Self Adapting- Percentage and Traditional Timer.

• Self Adapting-Midnight: Automatically adjust the dimming curve based on the on-time of the past two days (if the difference <15 minutes), assuming that the centre point of the dimming curve is midnight local time.
• Self Adapting-Percentage: Automatically adjusts the on-time of each step by a constant percentage = (actual on-time for the past 2 days if difference <15 min) / (programmed on-time from the dimming curve).
• Traditional Timer: Follows the programmed timing curve after powering on with no changes.

Output Lumen Compensation
Output Lumen Compensation (OLC) may be used to maintain constant light output over the life of the LEDs by driving them at a reduced current when new, then gradually increasing the drive current over time to counteract LED lumen degradation.

Minimum Dimming Level with 5% or 10% Selectable
The minimum dimming level can be set as 5% or 10% by Inventronics Multi Programmer,10% is default.

Hold Time Adjustable
When AC power is first applied to the LED driver, enabling a “Hold” period can allow devices powered by the Auxiliary voltage to stabilize before the driver fades up to the maximum dimming level. During this period, the driver will not respond to external dimming commands but will respond again after the hold time ends. Both the initial dimming percentage and the duration of this hold period can be adjusted by the Inventronics Multi Programmer. This function is disabled by default.
Fade Time Adjustable
There is a “Fade” period after the “Hold” period. The soft-start time and dimming slope applied to all dimming transitions can be adjusted individually. It is adjusted by the Inventronics Multi Programmer. This function is disabled by default.
End Of Life
End-of-Life (EOL) is providing a visual notification to a user that the LED module has reached the end of manufacturer-specified life and that the replacement is recommended. Once active, an indication is given at each power- up of the driver, which the driver indicates this through a lower light output during the first 1 minute before normal operation is continued.
Digital Dimming
Inventronics Digital Dimming is a UART (Universal Asynchronous Receive Transmitter) based communication protocol. Please refer to Inventronics Digital Dimming file for details.
Daisy Chain application
Daisy chain system can support synchronous dimming of up to 100 drivers due to unique dimming interface design, please pay attention to right sequence of ‘IN’ and ‘OUT’ port for RJ12 connection.

• Inventronics supports daisy chain connection for drivers that is dimmed by external controller. All drivers’ rotary switch need to be tuned to ‘EXT’.
• Inventronics offers the solution to use driver itself to control daisy chain dimming without the controller. The rotary switch of the master driver is tuned to required dimming level when the rest of drivers are tuned to ‘EXT’.

Note: The driver does not need to be powered on during the programming process.
