Delta DC Rectifier Repair/Refurbishment
Delta DC Rectifiers are used by original equipment manufacturers to build On-Site Sodium Hypochlorite Generator Systems. These power supplies are generally operated at full load for 24/7 operations at high temperatures. Hence, these power supplies must be extremely rugged and must be de-rated significantly to achieve long operating life.

MRI Power Supplies
MRI Power Supplies are used in MRI Imaging rooms in hospital environments. The lights in the MRI rooms require DC power. If AC power is used, the quality of the MRI imaging process is compromised. These units are ideal for the MRI room, where a 60 Hz flicker-free light environment is desired. CEHCO offers four models which are shown below.
