In the PSB50/40/30 series, several 0-10V dimming profiles can be selected, such as a logarithmic profile, a non-linear
profile with 1% minimum dimming and dim-to-off, and a non-linear profile with 10% minimum dimming and no dim-to-off.
Furthermore, every point in the non-linear dimming profile can be programmed using the programming software.
By default, the non-linear profile with 1% minimum dimming and dim-to-off (show in figure 1) is pre-loaded in the
PSB50/40/30 series.

+Dim Signal, -Dim Signal
The PSB50/40/30 series operate only with 0-10V dimmers that sink current. The method to dim the output current of the
driver is done via the +Dim/-Dim Signal pins. The +Dim/-Dim signal pins can be used to adjust the output setting via a
standard commercial wall dimmer, an external control voltage source (0 to 10 Vdc), or a variable resistor when using the
recommended number of LEDs. The dimming input permits 1% to 100% dimming.

In
fo
rm
Input Over Current Protection
The PSB series incorporates a primary AC line fuse for input over current protection to prevent damage to the LED driver
and meet product safety requirements as outlined in Section 6.
Short Circuit and Over Current Protection
The PSB50/40/30 series is protected against short-circuit such that a short from any output to return shall not result in a fire
hazard or shock hazard. The driver shall hiccup as a result of a short circuit or over current fault. Removal of the fault will
return the driver to within normal operation. The driver shall recover, with no damage, from a short across the output for an
indefinite period of time.
Internal Over temperature Protection
The PSB50/40/30 series is equipped with internal temperature sensor on the primary power train. Failure to stay within the
convection power rating will result in the power supply reducing the available current (fold back) below the programmed
amount. The main output current will be restored to the programmed value when the temperature of the built-in temperature
sensor cools adequately.
Output Open Load Protection
When the LED load is removed, the output voltage of the PSB50/40/30 series is typically limited to 1.3 times the maximum
output voltage of each model.
8 - OUTPUT POWER DE-RATING AT ELEVATED TEMPERATURES
The PSB50/40/30 series can be operated with cooling air temperatures above 50°C by linearly de‑rating the total maximum
output power (or current) by 2.5%/°C from 50°C to 70°C (see figure 2).

Dimming of the driver is possible with standard TRIAC-based incandescent dimmers that chop the AC voltage as
shown in Figure 3, or with ELV dimmers. During the rapid rise time of the AC voltage when the dimmer turns on,
the driver does not generate any voltage or current oscillations, and inrush current is controlled. During the ontime of the AC input, the driver regulates the output current based upon the conduction angle. The RMS value of
the driver output current is proportional to the on-time of the AC input voltage. When operating with an
incandescent dimmer, the RMS output current varies depending upon the conduction angle and RMS value of the
applied AC input voltage. Figure 4 shows the typical output current versus conduction angle at nominal input
voltage.
Forward-phase (TRIAC) and reverse-phase (ELV) dimming work only at 120 Vac.
The PSB50/40/30 series offers Tri-Mode Dimming™ compatibility with both phase-cut (reverse-phase and
forward-phase) and 0–10V dimmers. Phase-cut dimming always has priority over 0-10 V dimming.

The PSB50/40/30 series operate only with 0-10V dimmers that sink current. They are not designed to operate with
0-10V control systems that source current, as used in theatrical/entertainment systems. Developed in the 1980’s, the
0-10V sinking current control method is adopted by the International Electrotechnical Commission (IEC) as part of its
IEC Standard 60929 Annex E.
The method to dim the output current of the driver is done via the +Dim/-Dim Signal pins. The +Dim/-Dim Signal pins
respond to a 0 to 10 V signal, delivering 1% to 100% of the output current based on rated current for each model. A
pull-up resistor is included internal to the driver. When the +Dim wire (purple) is short circuited to the –Dim wire (grey)
or to the –LED wire (blue), the output current turns off.
If the +Dim input is > 10 V or open circuited, the output current is programmed to 100% of the rated current.
When not used, the –Dim wire (grey) and to the +Dim wire (purple) can be individually capped or cut off. In this
configuration, no dimming is possible and the driver delivers 100% of its rated output current.
The maximum source current (flowing from the driver to the 0-10V dimmer) supplied by the +Dim Signal pin is ≤ 1 mA.
The tolerance of the output current while being dimmed shall be +/-8% typical until down to 1.5 V.
In the PSB50/40/30 series, several 0-10V dimming profiles can be selected, such as a logarithmic profile, a non-linear
profile with 1% minimum dimming and dim-to-off, and a non-linear profile with 10% minimum dimming and no dimto-off. Furthermore, every point in the non-linear dimming profile can be programmed using the programming
software.
By default, the non-linear profile with 1% minimum dimming and dim-to-off (show in figure 5) is pre-loaded in the
PSB50/40/30 series. In this non-linear 0-10V dimming profile, 10V to 9.1V=100% of the output current, 1.5V to
0.55V=1%,
