DE90-3000 • Retrofit Kit for Strand Digital Environ DE90 Architectural Dimmer Rack

1.0 DE90-3000 - GENERAL

RetrofitDE90-3000 is a direct retrofit kit specifically designed for facilities with existing Strand DE90 architectural dimmer rack(s) requiring new, reliable and cost-effective control electronics.

Save time and money by retrofitting to current dimming technology with options equaling or exceeding those of most new dimming systems.

DE90-3000 has been designed with pin to pin compatibility with OEM factory wiring for ease of installation. Facilities can upgrade to this state-of-the-art technology in minutes with only a multi-screwdriver. Engineered with both the installer and end-user in mind, the DE90-3000 incorporates the following features:

1.1 DE90-3000 will offer compliance with the International Energy Agency's "One Watt Initiative" on stand-by power requirements (please refer to U.S. Executive Order #13221). Standby power on the DE90-3000 control electronic shall not exceed 1 Watt.

1.2 DE90-3000 shall employ a unique "lamp warming" technique that extends lamp life by limiting the in-rush current to cold lamp filaments by up to 70%.

1.3 An LCD user-interface for ease of set up and monitoring. All programming shall be via a user-friendly, intuitive and self-prompting menu structure. No PC or special software will be required.

1.4 Modular design of the unit shall make any potential service requirements fast and easy. The DE90-3000 control electronics shall be contained on a single plug-in PCB. This PCB shall contain all ancillary control electronics for the dimmer rack.

1.5 Dimmer control outputs shall be designed for precise and reliable control of the existing DE90 dimmer modules. It shall never be necessary to adjust ramp circuits for proper dimmer output.

1.6 The DE90-3000 shall accept dual independent DMX 512-A digital data protocol inputs allowing industry wide compatibility with modern control consoles. Both DMX inputs shall be independently opto-isolated from all other control circuitry, as well as from the DMX output ports. An internal protocol manager shall allow priority management or merging of both DMX inputs.

1.7 Optional node supports all major Ethernet protocols including Net2, Strand, ArtNet, ACN (Net3) and Pathport. Automatic recognition will permit interface to most popular lighting control protocols. It shall not be necessary to assign protocol.

1.8 An infrared LED link shall be provided on the control module face panel. This interface will permit hard copy printouts of all programmed data via an optional hand held infrared printer.

1.9 Rack thermal protection shall be employed via a mechanical relay interface to existing rack OEM thermal sensor. An active input shall cause an immediate disconnect of all dimmer control outputs.


The DE90-3000 control electronics are based on the MADD-24 (Multiple Application Dimmer Driver) design employed in JS-ICON dimmers racks and other 3000 Series products offered by Johnson Systems. The control electronics shall be contained in one plug-in PCB (MADD-24) and shall provide the following features:

2.1 The DE90-3000 shall be capable of controlling up to 24 dimmers in the DE90 dimmer cabinet. Advanced state-of-the-art voltage regulation hardware and software will ensure >1% all dimmer outputs. The DE90-3000 will operate with a voltage input range of 85-264VAC at 50 or 60Hz.

2.2 The DMX512 input ports shall accept two independent sources of DMX512 data protocol simultaneously from the system control console(s) or architectural control unit(s). The DMX inputs shall comply with USITT DMX512-A (ANSI E1.11 - 2008), standard protocol for digital data control.

2.3 It shall be possible to assign (patch) any dimmer control signal to any module position in the cabinet, thereby allowing dimmer modules of any rating to be used in any cabinet module location.

2.4 The DE90-3000 shall permit non-volatile storage all system configuration data. All data shall be protected from power failure by EEROM for a minimum of 100 years.

2.5 The ECU module shall accept up to 4 (four) analog inputs with the ability to be assigned to any of the 24 dimmer outputs in the system. Each analog input shall be selectable as either "Normal" mode (0-10VDC input) for dimmed applications or "Load Shed" mode (5VDC trigger) for power management interface to building management systems (BMS). The analog inputs shall function in a pile-on or HTP mode with the DMX control signal.

2.6 Dedicated dry contact inputs shall be provided for BMS, HVAC, security and fire alarm. Active security input shall "flash" any programmed dimmer outputs to a selectable level at a rate of 1Hz. Active fire alarm input shall bring any programmed dimmers to a selectable level and override all incoming control data.

2.7 Each individual dimmer in the dimmer cabinet shall be capable of being assigned one of four dimmer curves: incandescent square law curve, direct curve, linear curve, or non-dim (50% threshold with a 5% hysteresis).

2.8 The face of the control module shall include an LCD display and momentary push buttons for function select, parameter setting and feature monitoring. All programming shall be via a user-friendly, intuitive and self-prompting menu structure. It shall not be necessary to use a PC or any external programming devise to configure or set-up any function of the DE90-3000.

2.9 The MADD-24 control electronics shall employ the "system-on-a-chip" advanced digital technology. Such electronic circuitry shall permit real time signal monitoring and status LED indication to allow easy setup and remote troubleshooting.
