KEPCO SERIES MTW 146-1951
FLEXIBLE
MULTI-OUTPUT
POWER SUPPLIES
Kepco's Series MTW are 15, 30 and 60 Watt, triple-
output, affordable PC card-style RoHS (Reduction of
Hazardous Substances) compliant power supplies. All
three models produce 5 volts and ±12 volts d-c from
an a-c input that accepts 85-265V a-c. The 5V output
is isolated from the ±12V outputs and there is no
minimum loading requirement on any of the outputs.
All MTW models meet UL 60950-1.c-UL and TÜV
Rheinland EN60950 requirements. CE marked per LVD.
The MTW comply with all relevant EMI, Class B
conducted and ESD specifications.

(1) 5V output floating from ±12V outputs. AN ISO 9001 COMPANY
(2) Zener diode clamp method; protects load against faulty power supply; power supply cannot restart.
(3) 10 sec. max. Total power limited to 15, 30 and 60 watts respectively.
(4) Hiccup type; automatic recovery after cause of overcurrent is removed. Avoid overcurrent operation to prevent
component degradation.
