7087 Quad Fixed DC Power Supply Module

  • The 7087 is a quad DC power supply that provides four fixed independent floating supplies in one compact module. It is suitable for powering loop instrumentation and other devices. The voltage and current ratings are 6V (20A), 12V (10A), 24V (6A), 48V (3A).

    Operation is simple with the 6V control switch being the master to put the module in to standby. This enables the user to access the other supplies which can then be switched on and off individually. Each supply has its own switch, fuse and power LED indicator. Output connections are industry standard 4mm shrouded sockets spaced at 19mm centers.

    The supplies can be connected in series to obtain an alternative output voltage. However, the current rating is that of the lowest rated supply. The supplies must not be connected in parallel.
