Constant current led drivers psb Series


The ANSI C137.1 standard (currently in version ANSI C137.1-2022; available here) specifies the 0–10 V control interface method and performance requirements for dimmable LED drivers, fluorescent ballasts, and dimming control units where output power is adjustable between minimum/off and maximum via a control input signal. The interface may be from one or more control units to one or more drivers or ballasts.

Applications include—but are not limited to—commercial, residential, industrial, roadway and area, and hospitality. Applicable devices include—but are not limited to—dimmable drivers and ballasts that may be internal or external to luminaires, dimming controls, and daylighting controls.

This standard does not specify control by pulse-width modulation (PWM).

Compliance with this standard provides a documented means for manufacturers to specify values that designers and specifiers can use to assess interoperability.


The following image shows the dimming profile and voltage limits achieved by certain ERP Power 0–10 V dimmable drivers, which establish ANSI C137.1-2022 compliance. As shown below, the driver can go from dim-to-off mode below 0.5 V (500 mV).


The Lutron Athena wireless node is a radio frequency (RF) device that enables simple, digital control of individual light fixtures in an Athena control system. The small size and compatibility with a wide variety of drivers allow for seamless integration with common commercial lighting fixtures from any manufacturer.

The Athena wireless node works with the following LED driver types:

Tunable White Control –
Lutron DALI-2 digital LED drivers (LD2)
DALI-2 certified Type 8 LED drivers

Static White Control –
Lutron DALI-2 digital LED drivers (LD2)
DALI-2 certified LED drivers
ANSI C137.1 compliant 0–10 V LED drivers

ERP Power’s PSB, PHB, and PTB 0–10 V dimmable drivers are in compliance with ANSI C137.1 (as established above), and therefore can be used for static white control in conjunction with the Athena wireless node.
