Questions & Answers

Is this power pack damp or wet location rated? If not how can this rating be achieved?

Asked by: Alex
The Wattstopper BZ-50 power pack is not rated for damp or wet locations. It is UL 2043 plenum rated, which means it is suitable for use in air-handling spaces, but it does not have a rating for exposure to moisture. To achieve a damp or wet location rating, you would need to install the BZ-50 power pack inside a suitable enclosure that is rated for such environments.

What's the difference between bz 250 and bz 150?

Asked by: Leonardo
The Wattstopper BZ-150 and BZ-250 power packs are quite similar in functionality, but they differ in a few key aspects: 1. Voltage Range: -BZ-150: Operates with input voltages of 120/277 VAC. -BZ-250: Has a broader input voltage range, supporting both 120-277 VAC and 120-347 VAC for wider applications. 2. Load Switching: -Both units can switch a load of 20A at 120/277 VAC, but the BZ-250 also supports 120-347 VAC, making it suitable for higher voltage applications. 3. Application Flexibility: -The BZ-250 has additional support for plug loads (such as wall outlets), which expands its use beyond just lighting control. -The BZ-150 is more focused on lighting circuits, while the BZ-250 can manage lighting and plug loads. 4, Power-Up Options: -The BZ-250 features selectable power-up options that allow you to define whether the device will restore to On, Off, or its last state after a power failure, giving it an edge in more complex control environments. 5. Construction and Enclosure: -Both devices are plenum-rated, but the BZ-250 has a slightly larger form factor and additional options for grounding to ensure signal integrity. In summary, the BZ-250 offers more versatility with a broader voltage range, support for plug loads, and additional power-up options, while the BZ-150 is more streamlined for specific lighting applications.
