Description

The SUM-1K0SxxxMGR series is a 1000W, constant-current, programmable and IP66 rated LED driver that operates from 90-305Vac input with excellent power factor. Created for many lighting applications including high mast, sports, UV-LED, aquaculture and horticulture, etc. It provides 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 Programing Software.

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.

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 Programing 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.

Protection Functions

Note: When removing the protective cap of RJ12, the waterproof protection performance should be evaluated together with external connected system by users.

 Rotary Switch and RJ12 interface
Output current can be set as 0, 40%, 60%, 80%, 100% level by rotary switch and the output current can be dimmed by dimming wire in RJ12 connector when 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 zener.
3.  When 0-10V negative logic dimming mode and Dim+ is open, the driver will dim to off and be standby.

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

Note:

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 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 standby.

 Adjustable Dimming Curve
0-10V dimming curve can be set as corresponding dimming voltage by 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 zener.
3. When dimming voltage X point is set to be smaller than Y point, the dimming curve is positive logic, conversely, when X point is set to be bigger than Y point, the dimming curve is negative logic.
4. For best dimming accuracy, the difference between 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 AdaptingPercentage and Traditional Timer.

• Self Adapting-Midnight: Automatically adjusts the dimming curve based on the on-time of past two days (if difference <15 minutes), assuming that the center 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 power 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。

Daisy chain controlled by External Controller
Inventronics supports daisy chain connection for drivers that is dimmed by external controller. All drivers’ rotary switch need to be tuned to ‘EXT’.

Daisy chain controlled by Driver-self
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’.

Programming Connection Diagram

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