BCT40T converters are available in variants with a choice of two 4:1 input ranges ’24V’ (9 to 36Vdc) or ’48V’ (18 to 75Vdc).
Variants with single or dual outputs: 3.3V (10A), 5V (8A), 12V (3.33A), 15V (2.67A), 24V (1.67A), ±12V (±1.67A) or ±15V (±1.33A).
“Single-output models offer the flexibility of ±10% output voltage adjustment via an external trim resistor,” said the company.
At nominal input and full load, peak efficiency is 87 or 88% depending on version.
Also depending on version, maximum capacitive load is in the range 680 to 10,000μF.
Under-voltage lock-out is implemented and, for one second, input surges of just over double the nominal voltage can be tolerated.
The isolation barrier is rated at 2kVdc.
Operation is over -40 to +105°C ambient , but with derating to 0% at the top end (over-temperature protection activates when the metal case reaches 115°C).
Where this derating starts is variant-dependent: For 24V input versions it is between 50 and 60°C, while 48V types derate earlier, starting at between 35 and 50°C.
Other protections include continuous short-circuit with auto-recovery, and over-load activating at between 130% and 180%. A Zener clamp is included on the output.
For safety, they meet IEC/UL/EN62368-1 standards, as well as applicable CE and UKCA directives.
With additional components they comply with EN55032 Class A/B for conducted and radiated emissions, and EN61000-4-x for immunity.
Applications are expected in test, measurement, robotics, process control, analytical instruments, and communications equipment.
Warranty is three years.
As well as direct from the company, the dc-dc converters are available from Avnet Abacus, Digi-Key, Distrelec, Farnell, Mouser, RS and TME, and some regional distributors.
Last year, TDK-Lambda announced 200W non-isolated dc-dc converters in a 1 x 1inch format
