  • NIM and CAMAC Power Supplies

    W-IE-NE-R, Plein & Baus GmbH

    NIM and CAMAC crates require very clean and stable DC supplies with the standard voltages +24V / -24V, +12V / -12V and +6V / -6V. Consequently CERN defined compatible power supplies for both standards within their NIM and CAMAC specs., i.e. CERN spec. power supplies can be used on both types of crates. All "CE" version power supplies are outfitted wth separate AC wiring to comply with CE/UL safety standards.
