External supply promises long reliable life
Low-noise multipurpose power supply is fitted with field replaceable fan and air exhaust filters making it ideal for harsh and industrial environments.
DC/DC convertor is made for LED lighting
Wide input range DC/DC convertor provides a constant-current single output for powering a single LED or an array of up to nine devices.
Using industry standard I2C serial bus interface, the APC-SRM-R digital controller allows the operator to select each individual power module and adjust the voltage over output ranges of 23-29 or 46-58V DC in minimum 100mV steps.
Extremely compact with an ultra low 1U high profile, the APC-SCM-R measures just 482.6 x 43.56 x 84.29mm.
The easy-to-use unit gives simple module selection and voltage adjustment by front panel mounted rocker switches, while bright front panel LED displays provide the operator with a clear indication of module address and voltage plus the output current of the module being read.
Other features include automatic compensation for battery temperature while the status of other system-critical operating parameters can be taken directly from the power module rack.
The APC-SCM-R is easy to install with a 25-way D plug connection between the controller and back of the power shelf and is powered from the bus voltage of the system, thus dispensing with the need for an external power source.
Ideal for applications that are powered from a battery, AC/DC input, load sharing and low-voltage backup power systems, the APC-SRM-R can be used in a wide range of industries, such as telecomms, datacomms and industrial control.
