About the Crestron CSA-PWS2S-JBOX-ZUMLINK-CN

The unit has two outputs, and each can power a shade or additional Cresnet devices. Total output is 100 W (4.2 A) at 24 VDC, with 50 W (2.1 A) per output; for additional Cresnet devices the continuous total is 75 W at 24 VDC. Each motor has its own overcurrent protection, the output terminals have miswire protection, and two green LEDs show when 24 VDC is present on each shade output.

Two Cresnet connections, on paralleled 4-pin 3.5 mm terminal blocks, pass power and communication through to Cresnet products. Two Zūm Link RJ-45 ports allow in-room daisy-chaining of Zūm Link devices for commercial lighting applications that use custom programming. Crestron's instruction is not to combine shades and Cresnet devices on a single output: each shade or device needs its own dedicated output.

It runs from 100-240VAC, 50-60 Hz, through 18 AWG line and neutral flying leads and a 16 AWG ground lead, and mounts using screws on the back of the enclosure. The anodised black metal housing is designed to blend with open ceilings and meets UL 2043 requirements for environmental air-handling (plenum) spaces. Crestron states that it must be installed by a licensed electrician and comply with local building codes.

Questions about the Crestron CSA-PWS2S-JBOX-ZUMLINK-CN

What is the Crestron CSA-PWS2S-JBOX-ZUMLINK-CN?

It is a two-motor, junction box mounted power supply for Crestron shading. It powers up to two QMT series roller shade or drapery system motors at 24V, is plenum rated, and passes power through to two Cresnet or two Zūm Link connections for Crestron shade and Zūm lighting devices.

How much power does the CSA-PWS2S-JBOX-ZUMLINK-CN provide?

It provides 100 W (4.2 A) at 24 VDC in total, with 50 W (2.1 A) per output, both as limited power source (LPS) outputs. When the outputs power additional Cresnet devices, the continuous total is 75 W at 24 VDC. Input is 100-240VAC, 50-60 Hz.

Can shades and Cresnet devices share an output?

No. Each output can be used for either a shade or additional Cresnet devices, but Crestron says not to combine shades and Cresnet devices on a single output. Each shade or device must have its own dedicated output, and each motor is wired as a home run to the power supply.

Where can the power supply be mounted?

It is designed to be hardwired into a standard 4 in x 4 in junction box and mounts using screws on the back of the enclosure. It meets UL 2043 requirements for use in an environmental air-handling (plenum) space, is for indoor use only, and its anodised black metal housing is designed to blend with open ceilings.

What are the Zūm Link ports for?

The two RJ-45 Zūm Link ports allow in-room daisy-chaining of Zūm Link devices and pass through data from either the Cresnet ports or the Zūm Link ports. Crestron lists them for commercial lighting applications that use custom programming.

How much is the Crestron CSA-PWS2S-JBOX-ZUMLINK-CN?

Crestron asks its dealers to give the price of the CSA-PWS2S-JBOX-ZUMLINK-CN directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.

Can 1Install supply, install and programme the CSA-PWS2S-JBOX-ZUMLINK-CN?

Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the CSA-PWS2S-JBOX-ZUMLINK-CN on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.

Does the CSA-PWS2S-JBOX-ZUMLINK-CN come with a warranty?

Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the CSA-PWS2S-JBOX-ZUMLINK-CN develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.

Is the CSA-PWS2S-JBOX-ZUMLINK-CN in stock?

We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.

Can I buy the CSA-PWS2S-JBOX-ZUMLINK-CN without installation?

Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
