Discussion Overview

The discussion revolves around the compatibility between an Edwards 200H T pump and an EXDC160 controller, focusing on the voltage specifications of the pump and controller. Participants explore whether the differences in voltage ratings indicate distinct types of pumps or if they are solely related to the controllers used.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant notes that the Edwards 200H T pump is marked as a 24V pump, while the EXDC160 controller is rated for 80V, raising questions about compatibility.
  • The same participant speculates that the voltage ratings may pertain to the controllers rather than indicating different pump types, suggesting that EXC mains powered controllers output around 90V for all EXT pumps.
  • Another participant suggests contacting Edwards directly for clarification on the compatibility and voltage specifications.
  • A later reply indicates that Edwards confirmed the existence of both 24V and 80V pumps, stating that they require corresponding controllers.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the compatibility of the pump and controller before receiving a response from Edwards, but the later reply from Edwards suggests a clear distinction between the two types of pumps and their required controllers.

Contextual Notes

The discussion includes assumptions about the voltage ratings and their implications for pump compatibility, which remain unresolved until further clarification is provided.

TL;DR
24V /80V, what works with what pump?
I have an Edwards 200H T pump that came without a controller. I managed to get an EXDC160 for a good price, but I'm now concerned whether it is suitable for my pump. The pump is marked as NRA093000 which, as far as I can tell, is a 24V pump. The EXDC is D39641500 which is an 80V controller.
What I'm struggling to work out is whether there are 24V and 80V pumps, or if the different voltage rating is purely down to the controller fitted when new. It appears that the EXC mains powered controllers work for all EXT pumps and output ~90V, with no differentiation between 24V and 80V pumps, so I have a feeling 24V and 80V refer only to the supply voltage to the controller. Can anyone confirm this?

Those are very specific questions. I think you would get better answers by asking Edwards directly.
 
Thanks, I've fired a message off to Edwards, I'll post their response here when I receive it.
 
Edwards replied pretty promptly, it seems there are 24V pumps and 80V pumps and they need 24V or 80V controllers repsectively.
