PRODUCT SPECIFIC QUESTIONS
Is It possible for the customer to program or re-configure the load controller?
With the PowerCore 21 and PowerCore 14 solid state load controllers, the customers will have programming capabilities. The omni-BUSTM open source software and architecture offers almost unlimited feature development by any certified third-party.
Does the load controller offer a dimming feature?
Through its pulse-width modulation (PWM) technology, DSS is able to offer its customers the dimming function as an option. Additionally, backlights and indicators on the keypad can be pulse-width modulated to increase/decrease brightness. The solid state load controller uses power MOSFETs on all output functions, so each output has the capability to be PWM.
What type of protection is used in the load controllers?
Over current protection is accomplished by using current-sensing power MOSFETs for each output. The output current sensed by the MOSFET is read in by a microcontroller and compared to the trip current programmed for that circuit. If it is greater than the programmed value, the circuit is shut off and the corresponding LED on the keypad flashes to indicate a circuit fault to the user. The protection provided by Solid State reacts in micro seconds and affords a very high level of accuracy for maximum protection without mechanical fatigue. Circuit protection is maintained at the same level of accuracy for the entire life of the product.
What are the major differences of the PowerCore 21 and the PowerCore 14 solid state load controllers?
The PowerCore 14 provides more features and power in a modular product offering than the PC21. With a 6 output add-on module, the PC14 offers the same number of output circuits plus dedicated input circuits, 4 more ‘H’ bridges, 24 amps of power per output, connector flexibility, a second power grid, and more. The PC21 does offer a convenient single package for applications that require up to 21 circuits with power outputs of 15 amps or less.
There are DSS systems out in the field that uses a PowerCore 210, PowerCore 100 and even a PowerCore 16EM. Why does DSS no longer sell these products?
DSS no longer actively markets the older products but will continue to support existing customer requirements. All the functions and features of the discontinued products are available with our current products. With our commitment to customer service, we will continue to support and provide warranty product for applications using the discontinued product lines.
GENERAL QUESTIONS
The Digital Switching System (DSS) technology costs more than discrete switches. Why should a customer go with it?
Although the initial material cost for the DSS system might exceed that of discrete switches, the total cost of the acquisition is significantly less. Typically, the DSS solution reduces system wiring (and associated installation labor) by approximately 40 percent over discrete switches. Extra components required to deliver features such as timers, dimmers, ‘H’ Bridges are eliminated. These features are all enabled in software. Additionally, because the system is completely sealed and impervious to harsh environments, routine maintenance and warranty costs are greatly reduced.
What are typical applications for DSS?
The DSS technology is an ideal solution for marine, and transportation switching applications. However, customers from other industries have seen the huge benefits of our power distribution products and DSS currently has units installed on outdoor equipment, industrial, first responder, construction equipment, emergency vehicle, and recreational vehicle applications. Completely sealed and maintenance-free, the keypads and load controllers are designed to meet the harsh requirements imposed by these industries.
How reliable is the Digital Switching System technology?
Since 2002 after taking over the product line from Grayhill, DSS’ products continue to be a major system component to several high-profile customers, including Sea Ray and Correct Craft boats. Most of the historical and documented DSS returns have typically resulted from a component failure external to DSS. The single largest reason for returned parts is simply that dealers do not completely understand how the system operates. The key to reducing returns of DSS units is to ensure thorough training of service personnel.
I am interested in obtaining a sample DSS system for evaluation. How do I go about doing this?
Contact your local DSS sales representative to obtain a Sample Request Form (SRF). This form can also be
downloaded from our website. Complete the form and return it to DSS. DSS will respond with a Sample Proposal Document (SPD) that describes the sample to be built. Once the customer approves the SPD, DSS configures and ships the sample system to the customer. Depending on sample product availability, this whole process typically takes 2-3 weeks.
I have a limited budget for my switching needs. Is DSS the right solution for me?
DSS has a variety of solutions at different price points to meet every budget. We offer solutions at or below $15 per circuit depending on volume and options.
I am DIY hobbyist and want to retrofit my boat or vehicle. Does DSS have anything to offer?
DSS is planning on launching a retail ‘system in a box’ version of our product in 2011. It will consist of a load controller, a keypad, network cables and a generic wire harness as well as a software GUI application for field configuration. Stay tuned!
How big can a system be?
The DSS multiplex architecture is a multi-master, CAN or RS485 system. There can be technically 256 nodes on the bus. The system easily scales from one keypad and load controller to multiple input points and multiple load controllers all sharing the same message backbone. It can grow to cover almost any size of vehicle/craft.
DSS does not offer a display. How can I get a display to operate with your system?
DSS has developed all of its new products to be compatible with NMEA 2000 standards. The messages for Power Distribution are under development. Once released, these messages can be displayed by any manufacturer that incorporates them into their software/GUI release as Lowrance has done with the first set of test messages. Custom display interfaces such as those produced by Krill Systems can be used with our PowerGate 2000 gateway.
